  • Types and Characteristics of Locomotives Dr. Ahmed A. Khalil Steam Locomotives - Operating Principle
    Types and Characteristics of Locomotives Dr. Ahmed A. Khalil Steam Locomotives - Operating Principle: The wheel is connected to the rod by a crank. The rod is connected to the piston rod of the steam cylinder., thereby converting the reciprocating motion of the piston rod generated by steam power into wheel rotation. - Main Parts of a steam locomotive: 1. Tender — Container holding both water for the boiler and combustible fuel such as wood, coal or oil for the fire box. 2. Cab — Compartment from which the engineer and fireman can control the engine and tend the firebox. 3. Whistle — Steam powered whistle, located on top of the boiler and used as a signalling and warning device. 4. Reach rod — Rod linking the reversing actuator in the cab (often a 'johnson bar') to the valve gear. 5. Safety valve — Pressure relief valve to stop the boiler exceeding the operating limit. 6. Generator — Steam powered electric generator to power pumps, head lights etc, on later locomotives. 7. Sand box/Sand dome — Holds sand that can be deposited on the rails to improve traction, especially in wet or icy conditions. 8. Throttle Lever — Controls the opening of the regulator/throttle valve thereby controlling the supply of steam to the cylinders. 9. Steam dome — Collects the steam at the top of the boiler so that it can be fed to the engine via the regulator/throttle valve. 10. Air pump — Provides air pressure for operating the brakes (train air brake system). 11. Smoke box — Collects the hot gas that have passed from the firebox and through the boiler tubes.

Making its debut alongside the 4-4-0 at the Centennial Exhibition celebrating the United States' 100th anniversary, the 2-6-0 carried 4 million of the visitors around the Exhibition site. Its impressive size and strength led the engine to be christened the "Mogul," and the 2-6-0 reigned over the narrow gauge rails of its day. Bachmann's Spectrum@ 2-6-0 Mogul is a 1 :20.3 large scale reproduction of the revered Baldwin locomotive. It features prototypical detailing and parts, including a working Stephenson valve gear with operating piston valves, Johnson bar, and linkage.

Place the board on a hard surface and using a razor knife cut along the board edge. Carefully pull off the tape and plastic from the locomotive. Discard all tape and plastic. There is a small parts bag with the tools, tank caps and headlamp. General Information Operating a live steam model is different from an electrically powered version. It is a hands on interactive model. Never leave any working engines unattended once the burner is lit or if the locomotive is under way. Always know where and how the locomotive is operating including the boiler water levels. • Always read and understand the manual prior to operation for the first time. • Always maintain the lubrication on the motion parts and lubricator as it is designed for extended run times. The lubricator will last for about 45-60mins. • Never let the engine run completely out of water – if the locomotive suddenly stops and there is still pressure or if the glass is empty shut down the burner. DO NOT ADD WATER TO A HOT EMPTY BOILER • When filing the gas tank, keep away from any open flame or passing by locomotives, especially Alcohol fired locomotives.
