British Rail Class 92

The British Rail Class 92 is a class of dual-voltage electric locomotives that can run on 25 kilovolts alternating current from overhead wires or 750 volts direct current from a third rail, designed specifically for services through the Channel Tunnel between Great Britain and France. The fleet of 46 was built by a consortium of Brush Traction and ABB Traction, with final construction and commissioning at the Brush works in Loughborough between 1993 and 1996. ABB supplied the traction system, built around gate turn-off thyristor converters and its new microprocessor-based MICAS-S2 control system, giving a maximum power of 5 megawatts under the wires. Intended for freight and the never-introduced Nightstar sleeper trains, the class is now run by GB Railfreight and DB Cargo UK and has also worked the Caledonian Sleeper.
