Item 5.   Other Events.

          On September 14, 1998, a shareholder of Union Pacific Corporation
(the "Company") filed a purported derivative action on behalf of the
Company in the District Court for Tarrant County, Texas, captioned Stepak
v. Lewis, Cause No. 342-175282-98 (District Court of Tarrant County,
Texas), naming as defendants the Company, the Company's principal rail
subsidiary, Union Pacific Railroad Company ("UPRR"), and the current and
certain former directors of the Company. The derivative action alleges,
among other things, that the named current and former directors breached
their fiduciary duties to the Company by approving and implementing the
merger of Southern Pacific Transportation Company and its affiliated
railroads with UPRR without informing themselves of its impact or ensuring
that adequate controls were put in place and by causing the Company to make
misrepresentations about its service problems to the financial markets and
regulatory authorities. The defendants believe that these claims are
without merit and intend to defend them vigorously.
