The Eurotunnel Class 00310-4-0diesel locomotives were built by the Hunslet Engine Company between 1989 and 1990 for Channel Tunnel construction work and now used for maintenance duties. They were originally built as 900 mm (2 ft 11+7⁄16 in) gauge, and were subsequently rebuilt by Schöma to 1,435 mm (4 ft 8+1⁄2 in) standard gauge[1] in Germany between 1993 and 1994.
Twelve locomotives were built, numbered 0031–0042. They carry a yellow livery and are used by Getlink for shunting duties at Cheriton and Coquelles depots.
