The British Rail Class 456 was an electric multiple unit passenger train introduced by Network SouthEast on inner-suburban services in South London to replace the elderly Class 416 2EPB units.[3] Twenty-four two-car units were built by British Rail Engineering Limited's York Carriage Works in 1990 and 1991.[1]
Following the privatisation of British Rail, the fleet was sold to Porterbrook and operated by Southern up until late 2013, when they were transferred to South West Trains and heavily refurbished.[4][5] Routes that were operated by Class 456 units will be operated by new Class 701 Bombardier Aventra units in the future.[6]
