The SR electrified the London Victoria to Brighton line in the early 1930s, and full electric services commenced over the route from 1 January 1933.

A number have been returned to service on the main line with the Belmond British Pullman (previously the Venice Simplon Orient Express or VSOE), as hauled cars forming part of the British Pullman charter train.

By 2009, the trust had assembled a four-car set,[4] having acquired cars from the North Norfolk Railway and VSOE.

The table below sets out the current position: Hornby Railways produced OO gauge models of the 5-BEL from 2012, in both BR blue and grey and Pullman umber and cream liveries.
