}}BR Mk 1 Restaurant Miniature Buffet (RMB) 1853 was built at Wolverton in 1961 to diagram number 99 of lot number 30670, one of 82 such vehicles built in five lots from 1957 to 1962. One of the later lots, 1853 was built with Commonwealth bogies. The Miniature Buffet coach was designed to provide quick snacks, being staffed by only one attendant in service. The coach seats 44 passengers at tables, and also has bench seats opposite the serving area. Many RMBs have survived in mainline use or with heritage railways.

==Preservation==
Many RMBs have survived in mainline use or with heritage railways. 1853 arrived on the SVR in 1999 from Bounds Green Carriage Depot (London) via Holyhead, having been purchased by [[Severn Valley Railway (Holdings) PLC|SVR(H)]].<ref>SVR News 129</ref> It made a very unusual maiden voyage on the SVR. A then new EWS Class 66 locomotive, 66074, brought a train of 9 KPA bogie hopper wagons plus a KOA 'Piggyback' lorry transporter wagon onto the SVR on Saturday 17 March. The train ran the full length of the Railway to Bridgnorth. On the return trip which set off at 18:05 it dropped ballast at a number of locations, including south of Hampton Loade where the generators on board the Piggyback wagon were started up to demonstrate floodlight ballast dropping. The purpose of the trip was to demonstrate the system to representatives of Railtrack and GTRM. Newly arrived RMB 1853 was attached to the train to accommodate the press and observers, as it was still fitted with air brakes compatible with the wagons. The total loaded weight of the train including the Buffet Car was estimated at 585 tonnes making it probably the heaviest train to traverse the branch at any time in its history. After the ballast was discharged it weighed about 285 tonnes.<ref>SVR News 131</ref> 1853 is used in [[Carriages#Set_C|Set C]], the BR Crimson & Cream running set.
