The fleet of Class 423 '4-VEP' electric multiple units were built at BR York & Derby Works between 1967 and 1974. These 'slam-door' EMUs featured opening doors next to every seating area and were the last coaching stock in this format built for BR. They were mostly found working outer-suburban services in South London and rural services in Kent, Sussex and Hampshire. They remained in service on these lines for 38 years, before finally being replaced by Electrostar and Desiro EMUs in the mid-2000s. (Information provided via Wikipedia)
