Metropolitan Railway boxcab electric loco (nos 11-20)
The second ten, also constructed by Metropolitan Amalgamated, were built to a box car design with British Thompson Houston control equipment
Forward visibility on the camel-backs was not good,so this loco type had flat fronts. There were still some problems so when the next loco was designed(initially modifying one of each previous types) it had a V shaped front end to reduce wind noise.
Requires finishing off, wheels etc
Scale OO (1/76 4mm/ft)
