Serco Caledonian Sleeper Mk3a Lounge & Seated Cars (Mk5 Version)19th April 2022
The Mk3a carriages were constructed by BREL Derby Litchurch Lane Works between 1975 and 1984. The
Mk3a carriages are basically the locomotive hauled version of the Mk3 coaching stock used on InterCity
125 high speed trainsets, except that they have buffers and dropdown buckeye couplings fitted so that
they can be hauled by conventional locomotives.
Initially Second Open (SO) and First Open (FO) variants were constructed, followed by Restaurant First
Buffet (RFB) vehicles in 1979-80.
The carriages have been repainted in full Caledonian Sleeper livery as carried on CAF Mk5 carriages
that was introduced in 2019, a type of coach which has yet to be made available for Train Simulator.
