Railway Express Agency: The Railway Express Agency ("REA") was a national monopoly set up by the United States federal government in 1917.  Rail express services provided small package and parcel transportation using the extant railroad infrastructure much as UPS functions today using the road system.  The United States government was concerned about the rapid, safe movement of parcels, money, and goods during World War I and REA was its solution to this problem.  REA ceased operations in 1975, when its business model ceased to be viable.

Chicago, Milwaukee and St. Paul Freight House: The Chicago, Milwaukee and St. Paul Freight House is a historic former railway station in Stillwater, Minnesota, United States, built in 1883 as a passenger and freight depot for the Chicago, Milwaukee and St. Paul Railway (better known as the Milwaukee Road).  It was listed on the National Register of Historic Places in 1977 for having local significance in the themes of commerce, communications, engineering, and transportation.  Its notability derives in part from its long service to Stillwater; nearly all goods shipped to and from the city passed through this station, and up to the 1920s it hosted critical telegraph and Railway Express Agency offices.  The building is also noted as a somewhat rare example of a combination freight and passenger station, and for the engineering of its internal wood construction.  It is also a contributing property to the Stillwater Commercial Historic District.  The station closed in 1970 and now houses the Freight House Restaurant.

Railway Express Agency Building: The Railway Express Agency Building was a historic building located at 1804 Western Avenue in Mattoon, Illinois.

The Railway Express Agency provided rail express shipping services to Mattoon's citizens, allowing them to ship money and packages along Mattoon's two major railways, the Illinois Central Railroad and Cleveland, Cincinnati, Chicago and St. Louis (Big Four).  The agency formed in 1917, when the federal government ordered that all existing express services consolidate into a single service; this measure ensured consistent shipping of goods during World War I.  The agency shipped goods to and from Mattoon until 1964, when the Big Four went bankrupt; the building served as a freight depot until 1971.
