10. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement relating to such Securities or any Issuer Free Writing Prospectus, and provided, further, that the Company shall not be liable to any Underwriter under the indemnity agreement in this subsection (a) to the extent that (i) any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, (ii) the Company has informed the Underwriters of such untrue statement or alleged untrue statement or omission or alleged omission in writing at least 24 hours prior to the Time of Sale, (iii) the Company has filed on Form 8-K an amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus with the Commission correcting such untrue statement or alleged untrue statement or omission or alleged omission prior to the Time of Sale, (iv) the Company has provided to the Underwriters an amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus correcting such untrue statement or alleged untrue statement or omission or alleged omission at least 24 hours prior to the Time of Sale and

requested in writing that the Underwriters deliver such amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus to the persons to whom the Underwriters are selling the Securities, and (v) such loss, claim, damage or liability results from the fact that such Underwriter has sold Securities to a person to whom such Underwriter has failed to deliver such amended Preliminary Prospectus or Pricing Prospectus or Issuer Free Writing Prospectus.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Pricing Prospectus, the Registration Statement, the Prospectus as amended or supplemented, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the foregoing, in no event shall more than one such separate counsel in each jurisdiction where an action is commenced be retained for all indemnified parties together and neither the indemnified party nor the indemnifying party, in the instance where the indemnifying party has assumed the defense of the indemnified party, shall settle any action, proceeding or investigation with respect to the indemnified party without the written consent of the other, which consent shall not be unreasonably withheld.

(d) If the indemnification provided for in this Section 10 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters of the Securities on the other hand from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters of the Securities on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Underwriters on the other and the parties’ relative intent, prejudice resulting from any failure to give notice of any action under sub-section (c), knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Securities in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

(e) The obligations of the Company under this Section 10 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 10 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and manager of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

11. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, each as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Securities, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 8 hereof and the indemnity and contribution agreements in Section 10 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

12. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or manager or controlling person of the Company, and shall survive delivery of and payment for the Securities.

13. This Agreement shall be subject to termination by the Representatives by notice to the Company if, on or after the Time of Sale, there shall have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities; or (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; if the effect of any such event specified in this clause (iii) in the reasonable judgment of the Representatives, makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated by the Prospectus.

14. If this Agreement shall be terminated pursuant to Section 11 or Section 13 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities covered by this Agreement except as provided in Section 8 and Section 10 hereof; but, if for any other reason Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all reasonable out-of-pocket expenses approved in writing by the Representatives, including reasonable fees and disbursements of counsel, incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Securities except as provided in Section 8 and Section 10 hereof.

15. In all dealings hereunder, the Representatives shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in this Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the address of the Representatives as set forth in this Agreement; and if to the Company, shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement: Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 10(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

16. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 10 and Section 12 hereof, the

officers and managers of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

17. Time shall be of the essence of this Agreement. As used herein, “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto, or the financial, tax or other related consequences of the transaction for the Company.

19. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

20. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

21. This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

Burlington Northern Santa Fe, LLC

$500,000,000 Principal Amount of 3.250% Debentures due June 15, 2027

$750,000,000 Principal Amount of 4.125% Debentures due June 15, 2047

Ladies and Gentlemen:

We have acted as counsel for Burlington Northern Santa Fe, LLC, a Delaware limited liability company (the “Company”), in connection with the purchase by the several Underwriters (the “Underwriters”) listed in Schedule I to the Underwriting Agreement dated March 6, 2017 (the “Underwriting Agreement”), among the Company and ▇.▇. ▇▇▇▇▇▇ Securities LLC, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and ▇▇▇▇▇ Fargo Securities, LLC, as Representatives of the Underwriters, from the Company of $500,000,000 principal amount of the Company’s 3.250% Debentures due June 15, 2027 (the “2027 Debentures”) and $750,000,000 principal amount of the Company’s 4.125% Debentures due June 15, 2047 (the “2047 Debentures” and, together with the 2027 Debentures, the “Securities”) to be issued pursuant to an indenture dated as of December 1, 1995, between the Company (as successor to Burlington Northern Santa Fe Corporation, a Delaware corporation (the “Predecessor”)) and The Bank of New York Mellon Trust Company, N.A., as successor Trustee (the “Trustee”), the Fifth Supplemental Indenture, dated as of February 11, 2010, among the Predecessor, R Acquisition Company, LLC, a Delaware limited liability company (subsequently renamed Burlington Northern Santa Fe, LLC), and the Trustee (the Indenture, as so supplemented, the “Base Indenture”) and the Nineteenth Supplemental Indenture, dated as of March 9, 2017, between the Company and the Trustee (the “Nineteenth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including: (a) the Certificate of Formation of the Company (the “Certificate of Formation”); (b) the

Annex I-A-1

Amended and Restated Limited Liability Company Operating Agreement of the Company dated as of February 12, 2010, as amended (the “LLC Operating Agreement”); (c) resolutions adopted by the Board of Directors of the Predecessor on October 19, 1995 and February 11, 2010; (d) resolutions adopted by the Board of Managers of R Acquisition Company, LLC on November 2, 2009; (e) resolutions adopted by the Board of Managers of the Company on April 6, 2015 and April 18, 2016; (f) the officers’ certificate of the Company delivered to the Trustee pursuant to Section 301 of the Base Indenture in connection with the Nineteenth Supplemental Indenture and the Securities; (g) the Registration Statement on Form S-3 (Registration No. 333-211220) filed with the Securities and Exchange Commission (the “Commission”) on May 6, 2016 (the “Registration Statement”), for registration under the Securities Act of 1933 (the “Securities Act”) of an indeterminate amount of debt securities of the Company, to be issued from time to time by the Company; (h) the related Prospectus dated May 6, 2016 (together with the documents incorporated therein by reference, the “Basic Prospectus”); (i) the Prospectus Supplement dated March 6, 2017, filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act (together with the Basic Prospectus, the “Prospectus”); (j) the documents and other information described in Annex A to this letter (together, the “Specified Disclosure Package”); (k) the Underwriting Agreement; (l) the Base Indenture; (m) the Nineteenth Supplemental Indenture, and the forms of the Securities; and (n) the agreements specified on Annex B hereto (collectively, the “Specified Agreements”). In expressing the opinions set forth herein, we have assumed, with your consent and without independent investigation or verification, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as duplicates or copies. We have relied, with respect to certain factual matters, on statements of public officials and officers and other representatives of the Company and the representations and warranties of the Company and the Underwriters contained in the Underwriting Agreement, and have assumed compliance by each such party with the terms of the Underwriting Agreement. In particular, we have relied upon the Company’s representation that it has not been notified pursuant to Rule 401(g) of the Securities Act of any objection by the Commission to the use of the form on which the Registration Statement was filed. We have also relied upon advice from the Commission that the Registration Statement initially became effective on May 6, 2016.

Our identification of information as part of the Specified Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this opinion regarding the Specified Disclosure Package and is not the expression of a view by us as to whether any such information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Based on the foregoing and subject to the qualifications set forth herein, we are of opinion as follows:

1. Based solely on a certificate from the Secretary of State of the State of Delaware, the Company is a limited liability company validly existing and in good

Annex I-A-2

standing under the laws of the State of Delaware, with full limited liability company power and authority to own, lease and operate its properties and conduct its businesses as described in the Prospectus and the Specified Disclosure Package.

2. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

3. The Indenture has been duly authorized, executed and delivered by the Company, has been duly qualified under the Trust Indenture Act of 1939 (the “Trust Indenture Act”), and constitutes a legal, valid and binding obligation of the Company enforceable against it in accordance with its terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law); and the Securities have been duly authorized and executed by the Company and, when authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute legal, valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law).

4. The Securities and the Indenture conform in all material respects to the respective descriptions thereof contained in the Prospectus and the Specified Disclosure Package and the statements made in the Prospectus and the Specified Disclosure Package under the caption “Material United States Federal Income Tax Consequences”, insofar as they purport to describe the material tax consequences of an investment in the Securities, fairly summarize the matters therein described.

5. No authorization, approval or other action by, and no notice to, consent of, order of, or filing with, any United States Federal, New York State or, to the extent required under the Limited Liability Company Act of the State of Delaware, Delaware governmental authority is required to be made or obtained by the Company for the consummation of the transactions contemplated by the Underwriting Agreement, other than (i) those that have been obtained or made under the Securities Act or the Trust Indenture Act, (ii) those that may be required under the Securities Act in connection with the use of any “free writing prospectus” not listed on Annex A hereto and (iii) those that may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters.

6. The issue and sale by the Company of the Securities, the consummation of the other transactions contemplated by the Underwriting Agreement and the performance by the Company of its obligations under the Underwriting Agreement (i) do not violate

Annex I-A-3

the Certificate of Formation or the LLC Operating Agreement, (ii) do not result in a breach of or constitute a default under the express terms and conditions of any Specified Agreement, and (iii) will not violate any law, rule or regulation of the United States of America, the State of New York or the Limited Liability Company Act of the State of Delaware. Our opinion in clause (ii) of the preceding sentence relating to the Specified Agreements does not extend to compliance with any financial ratio or any limitation in any contractual restriction expressed as a dollar amount (or an amount expressed in another currency). We note that certain of the Specified Agreements are governed by laws other than New York law; our opinions expressed herein are based solely upon our understanding of the plain language of such agreements, and we do not express any opinion with respect to the validity, binding nature or enforceability of any such agreement, and we do not assume any responsibility with respect to the effect on the opinions or statements set forth herein of any interpretation thereof inconsistent with such understanding.

7. The Registration Statement became effective under the Securities Act on May 6, 2016, and, assuming prior payment by the Company of the pay-as-you-go registration fee for the offering of the Securities, upon filing of the Prospectus with the Commission the offering of the Securities as contemplated by the Prospectus became registered under the Securities Act; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Securities Act.

We express no opinion with respect to compliance with, or the application or effect of, Federal or state securities laws except to the extent set forth in paragraphs 3, 5 and 7 above.

We express no opinion with respect to compliance with, or the application or effect of, any laws or regulations relating to the ownership or operation of a railroad to which the Company or any of its subsidiaries is subject or the necessity of any authorization, approval or action by, or any notice to, consent of, order of, or filing with, any governmental authority, pursuant to any such laws or regulations.

We express no opinion herein as to any provision of the Indenture or the Securities that (a) relates to the subject matter jurisdiction of any Federal court of the United States of America, or any Federal appellate court, to adjudicate any controversy related to the Indenture or the Securities, (b) contains a waiver of an inconvenient forum or (c) relates to the waiver of rights to jury trial. We also express no opinion as to whether a state court outside the State of New York or a Federal court of the United States would give effect to the choice of New York law provided for in the Indenture or the Securities.

We understand that you are satisfying yourselves as to the status under Section 548 of the Bankruptcy Code and applicable state fraudulent conveyance laws of the obligations of the Company under the Indenture and the Securities, and we express no opinion thereon.

Annex I-A-4

We are admitted to practice in the State of New York, and we express no opinion as to matters governed by any laws other than the laws of the State of New York, the Limited Liability Company Act of the State of Delaware and the Federal laws of the United States of America.

We are furnishing this opinion to you, as Representatives, solely for your benefit and the benefit of the several Underwriters. This opinion may not be relied upon by any other person (including by any person that acquires the Securities from the several Underwriters) or for any other purpose. It may not be used, circulated, quoted or otherwise referred to for any other purpose.

Very truly yours,

Burlington Northern Santa Fe, LLC

$500,000,000 Principal Amount of 3.250% Debentures due June 15, 2027

$750,000,000 Principal Amount of 4.125% Debentures due June 15, 2047

Ladies and Gentlemen:

In that capacity, we participated in conferences with certain officers of, and with the accountants and counsel for, the Company concerning the preparation of the Prospectus Supplement dated March 6, 2017 (together with the related Basic Prospectus (as defined below), the “Prospectus”), relating to the Securities, filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act of 1933 (the “Securities Act”). The

Annex I-B-1

Prospectus was filed as part of the Registration Statement on Form S-3 (Registration No. 333-211220) filed with the Commission on May 6, 2016 for registration under the Securities Act of an indeterminate amount of debt securities to be issued from time to time by the Company (the “Registration Statement”), which Registration Statement includes a prospectus dated May 6, 2016 (together with the documents incorporated therein by reference, the “Basic Prospectus”), and we have assumed for purposes of this letter that the information in the Prospectus of the type referred to in Rule 430B(f)(1) of the General Rules and Regulations under the Securities Act was deemed to be part of and included in the Registration Statement pursuant thereto as of the Applicable Time (as defined below). The documents incorporated by reference in the Registration Statement, the Specified Disclosure Package (as defined below) and the Basic Prospectus were prepared and filed by the Company without our participation. For the purposes of this letter we have also reviewed the documents and other information described in Annex A to this letter (together, the “Specified Disclosure Package”). Our identification of information as part of the Specified Disclosure Package has been at your request and with your approval.

As Representatives of the several Underwriters

Ladies and Gentlemen:

This opinion letter is being rendered to you by me, as counsel to Burlington Northern Santa Fe, LLC, a Delaware limited liability company (the “Company”), pursuant to Section 9(d) of the Underwriting Agreement, dated March 6, 2017 (the “Underwriting Agreement”), between the Company and ▇.▇. ▇▇▇▇▇▇ Securities LLC, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC and ▇▇▇▇▇ Fargo Securities, LLC, as representatives of the several underwriters listed therein (the “Underwriters”), relating to the purchase by the Underwriters from the Company of $500,000,000 aggregate principal amount of the Company’s 3.250% Debentures due June 15, 2027 (the “2027 Debentures”) and $750,000,000 aggregate principal amount of the Company’s 4.125% Debentures due June 15, 2047 (the “2047 Debentures” and, together with the 2027 Debentures, the “Securities”). Capitalized terms used herein and not defined shall have the respective meanings assigned such terms in the Underwriting Agreement.

In rendering the opinions set forth below, I have examined originals or copies identified to my satisfaction of (i) the Underwriting Agreement; (ii) the registration statement on Form S-3 (File No. 333-211220) filed with the Securities and Exchange Commission on May 6, 2016 (the “Registration Statement”), for registration under the Securities Act of 1933 of an indeterminate amount of debt securities of the Company, to be issued from time to time by the Company; (iii) the Pricing Prospectus, as amended or supplemented; (iv) the Prospectus, as amended or supplemented; (v) the Indenture, as supplemented by the Fifth Supplemental Indenture, dated as of February 11, 2010, among Burlington Northern Santa Fe Corporation, R Acquisition Company, LLC and The Bank of New York Mellon Trust Company, N.A., as successor Trustee, (the “Trustee”), and the Nineteenth Supplemental Indenture, dated as of March 9, 2017, between the Company (as successor-in-interest to Burlington Northern Santa Fe Corporation) and the Trustee (as supplemented, the “Indenture”); (vi) the form of the Securities;

Annex II-1

and (vii) an officers’ certificate establishing the terms of the Securities pursuant to the Indenture. In expressing the opinions set forth below, I have assumed, with your consent and without independent verification, the authenticity and completeness of all documents submitted to me as originals and the conformity to authentic original documents of all documents submitted to me as duplicates or copies. With respect to certain factual matters, I have relied without independent investigation exclusively on statements or certificates of public officials and officers and other representatives of the Company. Any statements or opinions qualified by knowledge are limited to my actual, present knowledge, based on information provided to me pursuant to inquiry of officers and employees of the Company made in connection with the offering of the Securities. However, I have not undertaken any independent investigation to determine the accuracy of any such information.

Based upon and subject to the foregoing and the other qualifications and limitations stated in this opinion letter, I am of the opinion that:

1. The Company has the capitalization set forth in the Pricing Prospectus and the Prospectus, and all of the membership interests in the Company have been validly issued and are non-assessable;

2. The Company has been duly qualified as a foreign limited liability company for the transaction of business and is in good standing in the State of Texas;

3. BNSF Railway Company (“BNSF Railway”), a subsidiary of the Company, is validly existing as a corporation in good standing under the laws of the State of Delaware; and all of the issued and outstanding shares of capital stock of BNSF Railway have been duly and validly authorized and issued, are fully paid and non-assessable, and are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims;

4. To my knowledge and other than as set forth in the Pricing Prospectus and the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which the Company has reasonable cause to believe will individually or in the aggregate have a material adverse effect on the financial position, member’s equity or results of operations of the Company and its subsidiaries, taken as a whole; and, to my knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

5. Assuming due authorization and execution by the Trustee, the issuance and sale of the Securities and the compliance by the Company with all of the provisions of the Underwriting Agreement and the consummation of the transactions contemplated therein, to my knowledge, will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject (other than the Specified Agreements, as defined in the opinion delivered to the Underwriters by Cravath, Swaine & ▇▇▇▇▇ LLP on the date hereof), the effects of which would, in the aggregate, be materially adverse to the Company and its subsidiaries taken as a whole; and

Annex II-2

6. The documents incorporated by reference in the Pricing Prospectus and the Prospectus (other than the financial statements, notes, schedules and other financial data therein, as to which I express no opinion or belief), when they became effective or were filed with the Commission, as the case may be, appear to have complied as to form in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulation of the Commission thereunder.

In addition, based on information provided to me by officers and representatives of the Company in response to due diligence inquiries conducted in connection with the offering of the Securities as contemplated by the Underwriting Agreement, I do not know of any amendment to the Registration Statement required to be filed or of any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Prospectus or required to be described in the Registration Statement, the Pricing Prospectus or the Prospectus which are not filed or incorporated by reference or described as required.

In addition, I have, from time to time, reviewed certain documents incorporated by reference in the Pricing Prospectus and the Prospectus and engaged in discussions with officers of the Company regarding those documents. However, except as specifically noted above, I am not passing upon and assume no responsibility for the accuracy, completeness or fairness of the statements contained in those documents incorporated by reference in the Pricing Prospectus and the Prospectus, nor do I make any representation that I have independently verified or checked the accuracy, completeness or fairness of such statements. Notwithstanding the foregoing and based on information provided to me by officers and representatives of the Company in response to due diligence inquiries conducted in connection with the offering of the Securities, no facts came to my attention that caused me to believe that any of such documents (other than the financial statements, notes, schedules and other financial data therein, as to which I express no belief) contained an untrue statement of a material fact, or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made when such documents were so filed, not misleading.

I am an employee of BNSF Railway and in that capacity serve as Senior General Attorney of BNSF Railway. I am executing and delivering this opinion letter only in such capacity, and in accepting this opinion letter you agree that I shall not have personal liability for the opinions expressed herein.

This opinion letter is limited to the matters stated herein and no opinions may be implied or inferred beyond the matters expressly stated herein.

This opinion letter is limited to the Federal laws of the United States and the laws of the State of Texas, and I express no opinion as to the laws of any other jurisdiction.

Annex II-3

The opinions set forth in this letter are rendered as of the date hereof, and I undertake no, and hereby disclaim any, obligation to advise you of any changes in or new developments which might affect any matters or opinions set forth herein.

This opinion letter is being furnished only to you, is solely for your benefit, and is not to be used, quoted, circulated, relied upon or otherwise referred to by any other person (including any person purchasing any of the Securities from you) for any purpose whatsoever or by you for any purpose other than in connection with the transactions contemplated by the Underwriting Agreement without my prior written consent.

Very truly yours,
