The Lancaster wagon Co built ten vans for the M.R.W.A. in 1891. They were identical in design to those used by the G.S.R. , 14'-0" long with an 8'-0" wheelbase and 9'-5" high. They were originally numbered 1B-10B. A further four were built and the whole fourteen vans were renumbered 180-193 (date unknown). From 1912 these vans started to be converted to class BM although two (184 and 191) provided parts for BL class vans. Conversion to class BM was completed by 1927. After the conversion the vans were listed as 10'-3" high at the centre of the roof. The class was renumbered BM801-812 in 1932. A new van (813) was added to the class in 1934 by conversion of an HM class horsebox.
