"FM OP800"@en . "The OP800 was a lightweight, streamlined railcar built by the St. Louis Car Company in 1939. Fairbanks-Morse supplied the 800 hp (600 kW), five-cylinder 8 in \u00D7 10 in (203 mm \u00D7 254 mm) opposed piston engine prime mover. The units were configured in a highly-unusual 2-A1A wheel arrangement (later converted to 3-A1A) mounted atop a pair of road trucks, and equipped with a front swing coupler pilot."@en . "1939Z"^^ .
