The Class 90 is a British electric locomotive built to replace aging 1960s electrics on the West Coast Main Line. Following privatisation they can currently be found on express freight and heavy passenger duties.
A total of 50 Class 90s were built by BREL Works in Crewe between 1987 and 1990 and were designed for a top operating speed of 110mph (180 km/h), operating from 25 kV AC overhead power and producing 5,000 bhp (3,700 kW). The models were also fitted with a Time Division Multiplier (TDM) to operate push-pull trains with a DVT, enabling fast turnaround of passenger services and removing the need for the leading locomotive to ‘run round’ its coaching stock.
After privatisation of BR in 1996, half of the Class 90 fleet were transferred to freight traffic, reclassified as 90/1s and modified to operate at a lower speed. The remainder of the fleet was transferred to private operators, including DB Schenker, Virgin Trains and Greater Anglia. The latter company now operates 15 Class 90s on services between London Liverpool Street, Ipswich and Norwich.
