Train engine

Diesel Locomotives can be found sitting idle on railroad tracks throughout the Mojave Wasteland in Fallout: New Vegas. The locomotives appear to belong to the same railroad company, as they are all decorated in the same paint scheme. While an operational example cannot be found in the game, the Powder Gangers' objective to clear the railroad tracks suggest that they may still be used by the New California Republic.

Appearances
Diesel locomotives can be found on the rail lines around New Vegas. Two examples include a lone engine sitting outside of the entrance to Boulder City, and one attached to several boxcars in the Gypsum Train Yard.

Behind The Scenes
The locomotives are very similar in appearance to the iconic F-Unit series of locomotives manufactured between 1939 and 1960 by the General Motors corporation. While in our universe, these locomotives were gradually phased out of mainstream service in the 1970s, it appears that they were still operating late into the 21st century in the Fallout world.

The locomotive at the entrance to Boulder City is adorned with the logo for the fictional "Barstow Strong Express". This may be a reference to William Barstow Strong (1837-1914), former president of the real world "Atchison, Topeka & Santa Fe Railroad" (Now the "BNSF").
