Technical Data |
Built by Bombardier in Derby, England, the Class 377 third-rail DC, 4 car electric multiple units began service during 2002. They are a member of the Electrostar train family, the most numerous EMU built in post-privatisation Britain. Due to their high power consumption major upgrades were carried out to the 750V DC third-rail power system used on the Southern region. The trains are used extensively on services in south London and on rural commuter services throughout Sussex and Kent where they replaced the aging 4CIG and 4VEP slam-door stock. The Class 377 trains feature external CCTV, a disabled seating area, and toilets in both intermediate coaches. Dual voltage units are fitted with a high speed pantograph to allow operation under 25kV lines as well as the native third rail shoes.
