There were no mark 2 catering vehicles built new for service in Great Britain (A small number of mark 2D buffets were built for use in Ireland, however), due to the wealth of mark 1 kitchen and buffet vehicles available which were still relatively recently built at the time.
Around 1980, a few pressure ventilated mark 2C TSOs were converted to micro-buffet vehicles for use on the likes of West of England, Highland mainline and Transpennine services, and a small number of mark 2D micro-buffets were created for Edinburgh/Glasgow - Aberdeen push-pull services.
The mark 2F RMBs converted from First Opens for Crosscountry services came later, being converted in 1988/89 (and an additional batch in 1991).
Likewise, there were no mark 2 sleeper vehicles built; sleeper stock went directly from mark 1 to mark 3.
