Railway Express Agency, recognized by its REA, REAX, and REX reporting marks, was established in 1918 to provide nationwide express shipping over the railroad network, handling parcels, valuables, and freight for businesses and the public. Railway Express Agency trains for sale often feature express boxcars, baggage cars, and railroad equipment inspired by fast package delivery service operated alongside passenger trains throughout the United States.
REA express cars and freight equipment remain especially popular with collectors and model railroaders building passenger consists, mail trains, and mid-century railroad operations. These railroad models are commonly added to model trains focused on historic express freight transportation and classic American rail service.
