Midland “Red” Motor Services (BMMO & MROC)
Prototype, Development and Experimental Vehicles — Miscellaneous Information



With Birmingham and Midland Motor Omnibus Company Limited (BMMO—Midland “Red” Motor Services) being in the unique position of building their own vehicles, the company operated a wide range of prototype, development and experimental vehicles.

Until 1953/4, all of the companies development work was carried out at Bearwood depot, and such vehicles were tested on services operated from that garage. Following the redevelopment and reopening of their Central Works, BMMO moved the development work to the more modern facilities offered by that site and tested vehicles from a number of depots in the area.
