A total of 208 vehicles were built at Derby Works from 1982-1984 to the Mark 3A profile. They were introduced to replace the ageing fleet of Mark 1 vehicles built to several designs, which dated from the late 1950s and early 1960s. Of these were 90 SLE (numbered 10646-10734) with 13 berths, and 118 SLEP ("Sleeper Either Class with Pantry", numbered 10500-10617) with 12 berths and a compartment for an attendant.

As of 2006, the only mainline operators of these type of carriages are First Great Western and First ScotRail. The former uses them in the consist of the Night Riviera from London Paddington to Penzance. The latter uses them in the consist of the Caledonian Sleeper from London Euston to Glasgow, Edinburgh, Aberdeen, Inverness and Fort William.

Several carriages have found a new lease of life on heritage railways, where they provide sleeping accommodation for volunteers.
