Mini Locomotive

The UGEARS Mini Locomotive is a compact, rubber band-powered wooden train with 1930s styling: a locomotive plus an open coal tender that can carry a small toy, snack or note across the room. Wind it with 6-7 turns of the ratchet dial, flip the switch on top to On, and it travels over two meters. A gear block drives the wheels while a flywheel smooths the acceleration.
