Steam locomotives consume vast quantities of water because they operate on an open cycle, expelling their steam immediately after a single use rather than recycling it in a closed loop as stationary and marine steam engines do. Water was a constant logistical problem, and condensing engines were devised for use in desert areas.
Steam locomotive components. Main components found on a typical steam locomotive include: The main components of a typical steam locomotive. Click or hover over numbers to see names. ( enlarge) The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not ...
A steam locomotive from East Germany. This class of engine was built in 1942–1950 and operated until 1988. A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder.
Factor of adh. The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1962. The 25 Big Boy locomotives were built to haul freight over the Wasatch Range between Ogden, Utah ...
Traction engine. A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning 'drawn', since the prime function of any traction engine is to draw a load behind it.
A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat ...
Geared steam locomotive. A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design. This gearing is part of the machinery within the locomotive and should not be confused with the pinion that propels a rack locomotive along the rack ...
Live steam. A hand-crafted, coal-fired, 1:8 scale 2-10-0 'live steam' locomotive in 71⁄4 in ( 184 mm) gauge. A "high line" representation of a Whitelegg-designed Baltic Tank in LT&S Livery. This engine runs on a track gauge of 3.5 inches and is powerful enough to pull several people. High lines are a configuration of a continuously elevated ...
