The McKeen Motor Car Company of Omaha, Nebraska, was a builder of internal combustion-engined railroad motor cars (railcars), constructing 152 between 1905 and 1917. Founded by William McKeen, the Union Pacific Railroad's Superintendent of Motive Power and Machinery, the company was essentially an offshoot of the Union Pacific and the first cars were constructed by the UP before McKeen leased shop space in the UP's Omaha Shops in Omaha, Nebraska. The UP had asked him to develop a way of running small passenger trains more economically and McKeen produced a design that was ahead of its time. Unfortunately, internal combustion engine technology was not and the McKeen cars never found a truly reliable powerplant.
