The mid-1940s found the majority of North American railroads in the process of re-equipping their motive power fleets. The war effort had taken its toll on the steam locomotive and the rail lines were now looking at the diesel newcomer, which had proven itself during World War II. At the forefront was General Motors with their E and F series of passenger and freight locomotives. This series of models focuses on the year 1947 and highlights the motive power direction of some of America's most well known railways.
