24 Facts About Steam locomotive

Steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam.

Richard Trevithick built the first steam locomotive known to have hauled a load over a distance at Pen-y-darren in 1804, although he produced an earlier locomotive for trial at Coalbrookdale in 1802.

An early working model of a steam rail locomotive was designed and constructed by steamboat pioneer John Fitch in the US during 1794.

In 1830, the Baltimore and Ohio Railroad's Tom Thumb, designed by Peter Cooper, was the first commercial US-built locomotive to run in America; it was intended as a demonstration of the potential of steam traction rather than as a revenue-earning locomotive.

In Germany, the first working steam locomotive was a rack-and-pinion engine, similar to the Salamanca, designed by the British locomotive pioneer John Blenkinsop.

In Russia, the first steam locomotive was built in 1834 by Cherepanovs, however, it suffered from the lack of coal in the area and was replaced with horse traction after all the woods nearby had been cut down.

In 1838, the third steam locomotive to be built in Germany, the Saxonia, was manufactured by the Maschinenbaufirma Ubigau near Dresden, built by Prof.

The first Steam locomotive produced by Henschel-Werke in Kassel, the Drache, was delivered in 1848.

Steam locomotive generated in the boiler fills the space above the water in the partially filled boiler.

Chassis, or Steam locomotive frame, is the principal structure onto which the boiler is mounted and which incorporates the various elements of the running gear.

Steam locomotive is normally controlled from the boiler's backhead, and the crew is usually protected from the elements by a cab.

Later engines used pumps driven by the motion of the pistons, which were simple to operate, reliable and could handle large quantities of water but only operated when the Steam locomotive was moving and could overload the valve gear and piston rods at high speeds.

Factor that limits Steam locomotive performance is the rate at which fuel is fed into the fire.

Small dimples called "poling pockets" at the front and rear corners of the Steam locomotive allowed cars to be pushed onto an adjacent track using a pole braced between the Steam locomotive and the cars.

Early Steam locomotive designs using slide valves and outside admission were relatively easy to construct, but inefficient and prone to wear.

Steam-electric locomotive uses electric transmission, like diesel-electric locomotives, except that a steam engine instead of a diesel engine is used to drive a generator.

Tractive effort is a measure of the heaviest load a Steam locomotive can start or haul at very low speed over the ruling grade in a given territory.

Weight of the Steam locomotive is roughly proportional to the power output; the number of axles required is determined by this weight divided by the axleload limit for the trackage where the Steam locomotive is to be used.

The 10 WAGR S class locomotives were the only class of steam locomotive to be wholly conceived, designed and built in Western Australia, while the Midland workshops notably participated in the Australia-wide construction program of Australian Standard Garratts – these wartime locomotives were built at Midland in Western Australia, Clyde Engineering in New South Wales, Newport in Victoria and Islington in South Australia and saw varying degrees of service in all Australian states.

Steam locomotive was a familiar technology, adapted well to local facilities, and consumed a wide variety of fuels; this led to its continued use in many countries until the end of the 20th century.

Steam locomotive engines have considerably less thermal efficiency than modern diesels, requiring constant maintenance and labour to keep them operational.

Reciprocating mechanism on the driving wheels of a two-cylinder single expansion steam locomotive tended to pound the rails, thus requiring more maintenance.

The Steam locomotive shed at Wolsztyn is the last of its kind in the world.

Many steam locomotive toys have been made, and railway modelling is a popular hobby.
