The IMP is a small but solidly engineered half horsepower 7 1/4” gauge battery electric loco equally at home on a garden railway or trundling round your local club track. The IMP is designed by Colin Edmondson and shares the same ingenious bolt together design as the very popular Scamp. Controls are simple, a direction switch, a speed controller, a ‘dead man’s’ foot pedal, which cuts power if the driver isn’t on board, and a handbrake working on all four wheels. It takes only a few moments to detach the heavy battery box, making it a lot easier to transport the IMP in the back of the car when visiting other tracks.
The IMP is a bolt together build.
The IMP kit comprises all the laser cut steel parts to build the loco, the wheels fitted to the axles and the layshaft sprockets welded to the layshaft. Folding the bonnets requires the use of a workmate. The only optional extra is the slatted seat, which gives a lot more back support and adds £60 to the cost of the build. A shopping list at the end of the instructions tells you what else you need to buy, mostly from Ebay. A basic IMP can be built for around £1,000, and the build can take less than a week. A fully illustrated set of instructions guides you at every stage of the build, making the build suitable for those who have never attempted anything like this before. There is an active and very helpful Facebook group, the ‘Scamp Owners club’, which also caters for the IMP and the bigger TYKE.
