Midland Railway Class M 0-6-0 Steam Loco

Rapido Trains UK have announced the Samuel Waite Johnson designed Midland Class M 0-6-0 in OO gauge. Though the Class M was designed and primarily used as a freight locomotive, they were equipped to work vacuum-braked trains, so it was not uncommon for them to haul passenger services.  All but 10 of the Class M were built by outside contractors between 1892 and 1903.
Five were built for the Somerset and Dorset Joint Railway and several locos were also ordered on behalf of the Midland and Great Northern Joint Railway Committee. 
In 1923, the LMS inherited all of the surviving Midland locos in this condition, with the LNER taking charge of the remaining locos from the M&GNJR in 1936. The S&DJR engines had all been rebuilt as Class 3F by the time they became LMS stock in 1930.
