Steam Power
A steam locomotive is a steam engine, boiler, and other equipment assembled to produce a machine capable of movement on railroad tracks. A steam engine, on the other hand, is any machine that converts steam pressure into motion - typically using a piston cylinder method. Those machines that convert steam pressure into direct rotating energy are steam turbines.

Although it is not a scale reproduction of any particular engine, it has the same general appearance and eye-taking appeal of the picturesque old-timers so hard at work about the turn of the century.
The model is equipped with the linkmotion reverse gear perfected by George Stevenson for his famous locomotive, The Rocket, in the 1830s. This valve action, which also provides a variable steam cutoff, has played a historic role in steam-power development.
The engine is a double-acting noncondensing one that exhausts directly into the air with the familiar puff-pup of a donkey engine or steam shovel.
With its 1 3/4" cylinder bore and 1" piston stroke, and with 75 or 80 Ib. of steam in its boiler, the little engine will turn over at 1,500 r.p.m. Actual power will depend much on the boiler used and on the workmanship in the engine itself.
The design is for heavy duty, however, with main bearings and other working parts larger than scale, and the engine will stand up well under hard, continuous runs at full working load, developing enough power to drive a quite large model boat, a small dynamo, an air fan, or other light equipment of Fractional-horsepower rating.

Steam Engine
The rare interior shot of the main floor of Engine Co. 5’s quarters, known as “Central Station”. The tin ceiling, electric lights, storage cabinets and steam radiator pipes demonstrate an austere but classic design. The building, built in 1867, was the quarters of Ladder Co. 1 and Chemical Co. 1.
Engine 5, the self propelled engine, was placed in commission in 1903. The driver controlled steering and acceleration, while the stoker on the back step handled the brakes.
Hose 5 was next to the pumper, and Ladder 1 was across the floor.
The propeller remained in service with Engine 5 until 1924 when it was replaced by a motorized pumper. The cost of the unit was $9,000.00
