HNGR's new petrol loco

[Hancockshire]

Something I've been working on for two weeks that has been made out of bits. It uses one of Meldrew's gears, DPST switch & battery box. It features a scratch built chassis, uses a motor from an RC car, weighs 400g & runs on a set of re-gauged IP wheels. Anybody wants a guess(no pictures or clips until tomorrow). The winner gives themselves a pat on the back
