  • Built by: BREL

The British Rail Class 90 electric locomotives were built by BREL at Crewe in 1987-1990, weighing 84.5 tonnes and with a top speed of 110 mph (180 km/h). They operate from 25 kV AC overhead lines and produce 5,000 bhp (3,700 kW). The class is employed on express passenger and heavy freight trains. Fifty Class 90/0 locomotives were built in the late 1980s, numbered 90001-050. They were developed from the Class 87, with many improvements and new features. The Class 90s were primarily built to replace the ageing Classes 81, 82, 83, 84 and 85 dating from the early 1960s, which were prone to fire damage. The class is fitted with rheostatic brakes in addition to standard Westinghouse air brake equipment. A Time-Division Multiplexer (TDM) is fitted to enable two or more locomotives to work in multiple. It also allows a Class 90 to work a push-pull passenger train with a Driving Van Trailer (DVT), DBSO or Propelling Control Vehicle. A Class 90 with a rake of eight British Rail Mark 3 coaches and a Driving Van Trailer (DVT) will reach 60 mph (97 km/h) in just over 1 mile (1.6 km), and 100 mph (161 km/h) in another 1+⁄2 miles (2.4 km).|pre-text=|date=March 2011}}{{citation needed|reason= In
