ALCO MRS-1

History
Development
The Korean War and the intensification of the Cold War at the beginning of the 1950s caused the USATC to consider what it might need for a new land war in Europe. They came up with a requirement for a locomotive capable of running on the existing tracks of a wide variety of railway systems. Key parts of the specification included adjustable-gauge trucks, compact bodywork to fit restrictive loading gauges, and replaceable couplers to fit a variety of systems. The trucks accepted wheelsets between standard gauge 4 ft 8 1⁄2 in (1,435 mm) and 5 ft 6 in (1,676 mm), which encompasses the vast majority of the broad gauges in use worldwide, including those of the then Soviet Union (1,520 mm (4 ft 11 27⁄32 in)) and the Iberian peninsula (1,668 mm (5 ft 5 21⁄32 in)).
