Perhaps what UP is best recognized for is its appetite for large
power, which certainly matches its character. It holds the
record for the largest diesel and steam locomotives ever built (the steam issue
remains up to debate) in the way of the American Locomotive
Company’s (Alco) 4-8-8-4 “Big Boys” (behemoth steamers able to produce
some 135,000 pounds of tractive effort) and Electro-Motive's 6,600 horsepower
DD40AX “Centennial” diesel-electrics (which were essentially two SD40 models under one frame). These are not the only largest units the railroad operated, they also owned Alco’s massive model C855 monsters and experimented with a gas-turbine electric locomotive (GTEL) capable of 8,500 horsepower!
The Union Pacific we now know began to take shape in 1982
when it purchased rival Western Pacific giving it access to
northern California. Soon after this takeover it acquired the Missouri
Pacific to reach Chicago, St. Louis, and Texas. In 1988 the company
grew even larger when it purchased the Katy (the Missouri-Kansas-Texas
Railroad) and in 1995 did the same with the Chicago & North Western
Railway. Finally, just a year later in 1996 the UP purchased the
gigantic Southern Pacific, a one-time powerhouse that by then was a company far removed from its glory days prior to the 1970s, so much so that it had been purchased by the Denver &
Rio Grande Western in 1988.
The above map gives a family tree of the largest railroads which have made up Union Pacific. More information about each can be found in the below links:
Chicago & Eastern Illinois Railroad
Chicago & North Western Railway

Denver & Rio Grande Western Railroad
Missouri-Kansas-Texas Railroad (Katy)
Missouri Pacific Railroad
Pacific Electric Railway
St. Louis Southwestern Railway
Western Pacific Railroad
The future of the Union Pacific is as wide open as the great
western plains where the railroad operates. However, if the company’s
past is any measure of what may happen in the years ahead, I think we
can safely say that when the merger movement picks up again the railroad and its famous shield logo will continue to flank locomotives during their daily task of moving goods across the country. It is important to note the company's nod to its history. The railroad operates an impressive heritage fleet of original equipment from its streamlined business train clad in its classic Armour yellow and gray livery to its stable of steam locomotives maintained in Cheyenne, Wyoming.

Seven Great Vacation Regions
|Electro-Motive's massive DD40X, built during the late 1960s when manufacturers looked to see just how powerful they could build a diesel locomotive, was actually somewhat successful. UP #6900 is seen here in Salt Lake City on May 10, 1969 to participate in the centennial of the Transcontinental Railroad.|
This fleet includes the never retired 4-8-4 #844, 4-6-6-4 #3985, and the
recently acquired 4-8-8-4 "Big Boy" #4014. The latter is of particular
note; when Union Pacific officially announced its intentions to restore
this steamer on July 23, 2013 the railfan community was shocked and the
news made headlines in the media. The move from its longtime resting
place in Ponoma, California has also been widely watched and
documented. Few ever thought it possible to see a Big Boy
under steam again given their incredible size and the expense to do so.
The locomotive will likely take a number of years to be fully restored
but when she is plying the rails once more will certainly become the
star attraction of the fleet.
