Reading Railroad, recognized by its RDG reporting mark, was founded in the 19th century to transport coal and other freight from the Pennsylvania coal regions to markets along the East Coast while also operating passenger service throughout the Northeast. Famous trains such as the Crusader and the King Coal continue to make Reading Railroad trains for sale especially popular with collectors and model railroaders focused on anthracite railroads and classic eastern passenger operations.
RDG locomotives, hopper cars, passenger equipment, and freight rolling stock remain a favorite for layouts featuring coal traffic, transition-era freight service, and historic Pennsylvania railroading. These railroad models are commonly added to model trains centered on northeastern railroads and mid-century American rail transportation.
