A locomotive is a rail transport vehicle that provides the motive power for a train.If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.
MotivePower, Inc. (MPI) was an American manufacturer of diesel-electric locomotives. The company traces its history back to being a division of Morrison-Knudsen (MK) since 1972. [1] After MotivePower spun-off from MK, the company merged with the air brake manufacturer WABCO to form "Wabtec" in 1999, remaining as a brand of it.
The name Tom Thumb is forever associated with the B&O, as the first steam locomotive built in the United States for an American railroad. It was built strictly as a demonstrator, but it was succeeded by a series of similar locomotives (the "Grasshoppers" and the "Crabs") designed by Ross Winans, the first head of motive power on the railroad.

[31]: 96 Many of the earliest locomotives for American railroads were imported from England, including the Stourbridge Lion and the John Bull, but a domestic locomotive manufacturing industry was quickly established, with locomotives like the DeWitt Clinton being built in the 1830s. [33]
The Baltimore and Ohio’s P-7 class was a class of 20 Pacific type locomotives built in 1927. Named for the first 20 Presidents of the United States, they were the prime motive power for the B&O’s top passenger trains for 31 years. One example, Baltimore and Ohio 5300, the "President Washington", has been preserved.
Their nearest competitor was the American Locomotive Company (ALCO), who had produced diesel-electric switch engines since the mid-1920s, provided motive power for the Rebel streamliner trainsets in 1935, and started production of development design locomotives to compete with the E-units in 1939.
The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...
