British Rail Class 455

The British Rail Class 455 is a type of electric multiple unit drawing power from a 750 V DC third rail. Built by BREL at York works in the early and mid-1980s, they were initially categorised as Class 510 as the successor to the Class 508. They were used on suburban services in South London, by South West Trains and Southern. Southern does not have 455s anymore.
