                           REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentleman:

         We have acted as special Utah corporate counsel to Union Pacific
Corporation, a Utah corporation (the "Company"), in connection with a
Registration Statement on Form S-3 filed by the Company and Union Pacific
Capital Trust, a statutory business trust formed under the laws of the State of
Delaware (the "Trust"), with the Securities and Exchange Commission (the
"Commission") on May 1, 1998 and Amendment No. 1 thereto filed with the
Commission on July 24, 1998 (such registration statement, as so amended, being
hereinafter referred to as the "Registration Statement"), relating to the
registration under the Securities Act of 1933, as amended (the "Act"), of (i)
30,000,000 6 1/4% Convertible Preferred Securities (liquidation amount $50 per
Convertible Preferred Security) (the "Convertible Preferred Securities")
representing undivided preferred beneficial ownership interests in the assets of
the Trust; (ii) Convertible Junior Subordinated Debentures due 2028 (the
"Convertible Junior Subordinated Debentures") of the Company, which may be
distributed under certain circumstances to the holders of the Convertible
Preferred Securities; (iii) the shares of common stock, par value $2.50 per
share (the "Common Stock"), of the Company, issuable upon conversion of the
Convertible Preferred Securities and the Convertible Junior Subordinated
Debentures; and (iv) the Preferred Securities Guarantee of the Company.

         This opinion is being furnished in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Act.

         The Convertible Preferred Securities were issued pursuant to the
Amended and Restated Declaration of Trust, dated as of April 1, 1998, among the
Company, as sponsor, The Bank of New York, as property trustee, the Bank of New
York (Delaware), as Delaware trustee, and L. White Mathews, III, Gary M. Stuart,
and Joseph E. O'Connor, Jr. as trustees.

         In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Registration
Statement; (ii) a specimen certificate representing the Common Stock; (iii) the
Articles of Incorporation of the Company, as presently in effect; (iv) the
Bylaws of the Company, as presently in effect; and (v) certain resolutions of
the Board of Directors of the Company relating to the issuance of the
Convertible Preferred Securities and the shares of Common Stock issuable upon
conversion thereof and related matters. We have also examined originals or
copies, certified or otherwise identified to our satisfaction, of such records
of the Company and such agreements, certificates of public officials,
certificates of officers or other representatives of the Company and others, and
such other documents, certificates and records as we have deemed necessary or
appropriate as a basis for the opinions set forth herein.

         In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies and the
completeness and authenticity of the originals of such latter documents. In
making our examination of documents executed or to be executed by parties other
than the Company, we have assumed (i) that each such party has satisfied those
legal requirements that are applicable to it to the extent necessary to make
such documents enforceable against it, including without limitation due
authorization by all requisite action, corporate or other, and due execution and
delivery of such documents, and (ii) the validity and binding effect thereof. As
to any facts material to the opinions expressed herein which we have not
independently established or verified, we have relied, without investigation or
independent verification, upon statements and representations of officers and
other representatives of the Company and others.

         Members of our firm are admitted to the bar in the State of Utah, and
we do not express any opinion as to the laws of any other jurisdiction. We
express no opinion as to, and assume compliance with, any applicable federal or
state securities laws.

         Based upon and subject to the foregoing, we are of the opinion that the
shares of Common Stock issuable upon conversion of the Convertible Preferred
Securities and the

Convertible Junior Subordinated Debentures have been duly authorized and
reserved for issuance upon conversion and, when certificates representing the
Common Stock in the form of the specimen certificates examined by us have been
manually signed by an authorized officer of the transfer agent and registrar for
the Common Stock and are issued upon conversion of the Convertible Preferred
Securities and the Convertible Junior Subordinated Debentures, such shares of
Common Stock will be validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement. We also consent to the reference to
our firm under the caption "Legal Matters" in the Registration Statement. In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

                                                Very truly yours,
