It is quite sad that these days we hardly see model steam engines running on steam, with compressed air providing the power. This engine, however, is a compressed air engine. Pneumatic motors have existed in many forms over the past two centuries, ranging in size from hand-held motors to engines of up to several hundred horsepower. Some types, as here, rely on pistons and cylinders; others on slotted rotors with vanes (vane motors) and others use turbines. Pneumatic motors have found widespread success in the hand-held tool industry, but are also used stationary in a wide range of industrial applications. Also onboard ships for starting diesel engines, for  example.
