The McKeen Railmotor was a 6-cylinder self-propelled railcar or railmotor. When McKeen Company of Omaha, Nebraska, U.S.A., first unveiled the car in 1905, the McKeen was among the first engines with a distillate-fueled motor. Revisions to the McKeen car led to the modern self-propelled gasoline rail-motor vehicle, and the "contours of the porthole windows, the front-mounted gasoline engines, and other features anticipated the streamline concept."
