The EMD DDA40X is a 6600 hp D-D locomotive, built from 1969 to 1971 exclusively for the Union Pacific Railroad. It is the most powerful diesel-electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. Union Pacific has marked DD40X on the cab exteriors, while EMD literature inconsistently refers to this model as either DD-40X or DDA40X. UP's DDA40X locomotives were the ultimate culmination of the company's experiments with extremely powerful locomotives that began with its gas turbine-electric locomotives and DD35s. For manufacturer EMD, the construction of the world's most powerful single frame locomotive was a sign of the company's dominance of the North American diesel locomotive market, with only GE Transportation an equal competitor. The DDA40X also pioneered a number of new technologies that would go on to be incorporated in future EMD designs.
The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation between December 1938 and November 1953. Final assembly was at EMD's plant at LaGrange (McCook) Illinois. The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC and SW. The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, with a gap in production between March 1943 and September 1945 due to World War II.

The Corpus Christi Terminal Railroad is a terminal railroad originally created in 1924 to facilitate heavy bulk freight cargo traffic flow from the recently completed deep water port channel of the new Corpus Christi Port. Wishing to maximize freight handling potential while holding down rates, the Port Authority decided to allow traffic to all of its docks and facilities by no less than three competing railroads, the Southern Pacific, the Missouri Pacific and the Tex-Mex railroads. To accomplish this, the Port of Corpus Christi Authority built its own trackage along the channel and to the docks and allowed all three carriers access to it. While the Authority's scheme at first heightened tensions between the three railroads, they eventually began to cooperate, assuring a good flow of bulk freight and the eventual success of the Port facilities.
