Class 154 BREL prototype Sprinter
In 1984 BREL built two prototype second generation
Class 150 DMUs.
Unit 150002 had Rolls Royce engines (later Perkins), Self Changing Gears transmission and Gmeinder final drives. Unfortunately this was not a very successful unit and was therefore chosen to evaluate a number of innovations. Following unsuccessful trials with its original equipment, it was withdrawn from service and fitted with Twin Disc hydraulic 'hot shift' gearboxes which were equipped with a new control system. This type of gearbox had been originally fitted to the prototype Class 151 units but had been beset with teething problems. The unit was also used as the test bed for the air conditioning eventually fitted to the Class 158 units. |
Here are a few pictures of the 154 prototype on test and in traffic.

Model As far as the author is aware MTK were the only company to make a kit for the Class 150. As you will see from the pictures the design was the fore-runner for a number of units both DMU and EMU's. However DC Kits market a number of DMU kits in '00' gauge and are always open to suggestions for future models, so you never know! More will be added as time permits, but if anybody has any photos of the prototype 154 unit in former days and would wish them to be included then let me know, all credited to the photographer of course! |
