The British Rail Class 423, electric multiple unit passenger trains were mostly built by British Rail (BR) at York Works from 1967 to 1974, although the MBSOs and TSOs of the first 20, 7701-7720, were built at Derby Works. They have manually opening doors next to every seating row and were the last coaching stock built in this pattern for BR. They were mostly found working outer-suburban services in South London and rural services in Kent, Sussex and Hampshire, up to 2005 when they were finally replaced by Electrostar and Desiro units. The fleet had a working life of 38 years.

The Bombardier Electrostar is a family of electric multiple-unit (EMU) passenger trains manufactured by Bombardier Transportation at their Derby Litchurch Lane Works in England between 1999 and 2017. It has become the most common new EMU type in the United Kingdom since the privatisation of British Rail with a number of variants. Electrostar trains are most common on high-volume suburban commuter routes around London; and on mainline services from London south to Surrey and the south coast, east to Essex, and north to Cambridge and Stansted Airport.
