The EMD F3 is a 1,500 horsepower diesel locomotive built by General Motors' Electro-Motive Division between 1945 and 1949.   The F3 was the third model in EMD's successful F-unit series of cab unit diesels, and it was the second most produced of the series behind the F7.  The F3's were widely used in both freight and passenger service, and in total, EMD built more than 1,100 A-units and almost 700 B-units. 

In this production, we are modeling A and B-units from nine railroads with prototypically accurate road numbers and paint schemes.  We are offering A-B sets with Powered A-units (w/ Paragon4 Sound) and unpowered B-units, and also separate single A and B-units with our full Paragon4 DC/DCC/Sound system.  All of our models have road-specific details and lighting.
