The OP800 was a lightweight, streamlined railcar built by the St. Louis Car Company in 1939. Fairbanks-Morse supplied the 800 hp, five-cylinder 8 x 10 opposed piston engine prime mover. The units were configured in a highly-unusual A1A-2 wheel arrangement mounted atop a pair of road trucks, and equipped with a front drop coupler pilot. The aft section was segregated into two separate compartments: one was used to transport baggage and the other served as a small railway post office, or RPO (the forward door, located just behind the radiator louvers, was equipped with a mail hook).

A total of 6 units, accompanied by matching trailing car sets, were manufactured exclusively for the Southern Railway (SR). Four of the OP800s were scrapped in 1955 (selected parts were retained for maintenance use on other SR F-M motive power), while the other two were sold off to the Georgia and Florida Railroad and Georgia Northern Railway as maintenance cars.

There are no OP800 units known to survive in any shape or form.
