POWER OF ATTORNEY

Know all by these presents, that the undersigned hereby makes, constitutes and
appoints each of Christian Lucky, Michael Donfris and Kim Moore, signing
singly, the undersigned's true and lawful attorneys-in-fact to:
1. Execute for and on behalf of the undersigned, in the undersigned's capacity
as an officer, director and/or ten percent stockholder of The Greenbrier
Companies, Inc., an Oregon corporation (the "Company"), Forms 3, 4, and 5 in
accordance with Section 16(a) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the rules thereunder, Form 144 in accordance
with Rule 144 under the Securities Act of 1933, as amended (the "Securities
Act"), and Form ID to obtain EDGAR codes and related documentation for use in
filing Forms 3, 4 and 5 and Form 144;
2. Do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete and execute any such Form 3, 4, or 5
or Form 144 or Form ID, complete and execute any amendment or amendments
thereto, and timely file such form with the United States Securities and
Exchange Commission and any stock exchange or similar authority; and
3. Take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, including
without limitation serving as EDGAR account administrator to manage the
undersigned's EDGAR account, it being understood that the documents executed
by such attorney-in-fact on behalf of the undersigned pursuant to this Power
of Attorney shall be in such form and shall contain such terms and conditions
as such attorney-in-fact may approve in such attorney-in-fact's discretion.
4. Seek or obtain, as the undersigned's attorney-in-fact and on the
undersigned's behalf, information regarding transactions in the Company's
securities from any third party, including brokers, and the undersigned
hereby authorizes any such person to release any such information to such
attorney-in-fact and approves and ratifies any such release of information.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in connection with the exercise of any of
the rights and powers herein granted, as fully to all intents and purposes
as the undersigned might or could do if personally present, with full power
of substitution or revocation, hereby ratifying and confirming all that such
attorney-in-fact, or such attorney-in-fact's substitute or substitutes, shall
lawfully do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted. The undersigned acknowledges that the
foregoing attorneys-in-fact, in serving in such capacity at the request and
on the behalf of the undersigned, are not assuming, nor is the Company
assuming, any of the undersigned's responsibilities to comply with, or any
liability for the failure to comply with, any provision of Section 16 of
the Exchange Act or with Rule 144 under the Securities Act.

The undersigned agrees that each such attorney-in-fact herein may rely entirely
on information furnished orally or in writing by the undersigned to such
attorney-in-fact. The undersigned also agrees to indemnify and hold harmless
the Company and each such attorney-in-fact against any losses, claims, damages
or liabilities (or actions in these respects) that arise out of or are based
upon any untrue statement or omission of necessary facts in the information
provided by the undersigned to either such attorney-in-fact for purposes of
executing, acknowledging, delivering or filing Forms 3, 4 or 5 or Form 144
(including amendments thereto) and agrees to reimburse the Company and each
such attorney-in-fact for any legal or other expenses reasonably incurred in
connection with investigating or defending against any such loss, claim damage,
liability or action.

This Power of Attorney does not relieve the undersigned from responsibility
for compliance with the undersigned's obligations under the Exchange Act,
including, without limitation, the reporting requirements under Section 16
of the Exchange Act. Additionally, although pursuant to this Power of
Attorney the Company will use commercially reasonable best efforts to timely
and accurately file Section 16 reports on behalf of the undersigned, the
Company does not represent or warrant that it will be able to in all cases
timely and accurately file Section 16 reports on behalf of the undersigned
due to various factors, including, but not limited to, the shorter deadlines
mandated by the Sarbanes-Oxley Act of 2002, possible time zone differences
between the Company and the undersigned and the Company's need to rely on
others for information, including the undersigned and brokers of the
undersigned.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 and Form 144 with
respect to the undersigned's holdings of and transactions in securities issued
by the Company, unless earlier revoked by the undersigned in a signed writing
delivered to each of the foregoing attorneys-in-fact. This Power of Attorney
revokes all previous powers of attorney with respect to the subject matter
of this Power of Attorney.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 25th day of March, 2025.
