The ALCO MRS-1 was a diesel-electric military road switcher designed for the United States Army Transportation Corps in the early 1950s. The Army wanted a locomotive that could run on the tracks of almost any railway system in a European war, so it asked for adjustable-gauge trucks, compact bodywork for tight loading gauges and swappable couplers. General Electric and General Motors each built a sample batch of thirteen in 1952, and the GE design, actually built by ALCO as a subcontractor, won a further order of 70. Most spent years in storage, were later used on military bases and Navy sites, and thirteen went to the Alaska Railroad. Several survive in museums.
