There are two basic areas of activity on a steam locomotive: the boiler where steam is made, and the engine (cylinders, rods, and driving wheels) where steam is used. The essential action of any steam engine, stationary or mobile, is that of steam under pressure (200-300 PSI for most locomotives) entering a cylinder-piston assembly and pushing

Notes - Steam Oil Selection

Small scale live steam locomotives (32 &45mm) never require boiler pressures in excess of 100psig, and most operate at pressures below 65psig. In the full scale steam trade, steam produced at these pressures is known as low pressure steam (below 150psig), and as wet and very wet steam.
