EMD FT36HCW-2

The EMD FT36HCW-2, classified as the Class 7000 under Korail, was a Korean semi-high-speed diesel-electric locomotive built to make Saemaul Class trains more streamlined before the 1988 Olympics. Fifteen were built between 1986 and 1987: units 7001 to 7009 entered service in June 1986 and units 7010 to 7015 in July 1987 with some small changes. It could only haul passenger cars. Its braking was electric, unlike the air brakes of the larger GT26CW, and dynamic braking was later prohibited because of ageing traction motors. The cab had windows on only one side, which limited slow-speed top speed to 25 kilometres per hour. Head-end power caused noise and maintenance problems, so Korail removed it and used dynamo cars instead. The original EMD 16-645F3B engines of 3500 horsepower were replaced by more efficient 3000 horsepower EMD 16-645E3 engines. Units 7001 to 7009 were retired in 2011 and 7010 to 7015 in November 2012, and unit 7001 was slated for preservation.
