Locomotive

A locomotive is a railway vehicle that provides the motive power for a train. The word originates from the Latin loco – "from a place", ablative of locus, "place" + Medieval Latin motivus, "causing motion", and is a shortened form of the term locomotive engine, first used in the early 19th...

s produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD).

Streamlined power cars and early experimental locomotives

EMC participated in the construction of a number of motorized railcars, integrated streamliner trainsets, and experimental locomotives in the 1930s. Most of these were short production runs (one, two, or four units) that were used by a single railroad. The vast majority consisted of Winton prime movers and General Electric generating, control and transmission components inside a carbody whose assembly was subcontracted to another manufacturer, since EMC did not have the ability to build its own bodies until 1936.

Trivia

The Train in Team Fortress 2 resembles a EMD GP9, and bears the company name "Northern Express". Sharing its paint scheme as well, this is likely a nod at real-life American railroad, Southern Pacific.
