A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks , instead of a more traditional tender . Most tank engines also have bunkers (or fuel tanks ) to hold fuel; in a tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also.
67-419: The Waimate Branch was a branch line railway built in southern Canterbury , New Zealand to link the Main South Line with the town of Waimate , the centre of the surrounding rural area. It opened in 1877 and operated until 1966; for some of this time, it included an extension to Waihao Downs that was known as the Waimate Gorge Branch or Waihao Downs Branch . When the line closed, Waimate received
134-430: A bunker is used to carry the fuel (for locomotives using liquid fuel such as oil , a Fuel tank is used). There are two main positions for bunkers on tank locomotives: to the rear of the cab (as illustrated in the left of the images below), a position typically used on locomotives with a trailing carrying axle or a trailing bogie ; or on top of and to one side of the firebox, a positioning typically used in cases where
201-518: A 'well' on the underside of the locomotive, generally between the locomotive's frames. This arrangement was patented by S.D. Davison in 1852. This does not restrict access to the boiler, but space is limited there, and the design is therefore not suitable for locomotives that need a good usable range before refilling. The arrangement does, however, have the advantage of creating a low centre of gravity , creating greater stability on poorly laid or narrow gauge tracks. The first tank locomotive, Novelty ,
268-553: A certain industrial site such as a power station either because of a location away from the main line or to reduce congestion. They were typically built to lower standards, using lighter rail and shallow roadbeds when compared to main lines. Much of Canada's branch line history relates to large rail transport conglomerates (such as the Grand Trunk , Canadian National , or Canadian Pacific ) which would acquire formerly independent short line railways for use as branch lines, with
335-529: A curve (like an inverted 'U'), or even an ogee shape (a concave arc flowing into a convex arc). Walter Nielson patented the saddle tank arrangement in 1849. Saddle tanks were a popular arrangement especially for smaller locomotives in industrial use. It gave a greater water supply, but limited the size of the boiler and restricted access to it for cleaning. Furthermore, the locomotive has a higher centre of gravity and hence must operate at lower speeds. The driver's vision may also be restricted, again restricting
402-462: A derailment. Some tram engines were fitted with a roof and enclosed sides, giving them an appearance more like a goods wagon than a locomotive. Railway locomotives with vertical boilers universally were tank locomotives. They were small, cheaper-to-operate machines mostly used in industrial settings. The benefits of tank locomotives include: There are disadvantages: Worldwide, tank engines varied in popularity. They were more common in areas where
469-579: A full cab, often only having a front ' spectacle plate '. If a cab was provided it was usually removable along with the chimney, and sometimes the dome, so that the locomotive could be loaded onto a flatbed wagon for transport to new locations by rail whilst remaining within the loading gauge . Steam tram engines, which were built, or modified, to work on a street, or roadside, tramway were almost universally also tank engines. Tram engines had their wheels and motion enclosed to avoid accidents in traffic. They often had cow catchers to avoid road debris causing
536-680: A guard's van. Two proposals for an extension were made, of which only one eventuated. The plan which did not eventuate was to link Waimate to either Duntroon or Livingstone . One of the proposals for the Otago Central Railway was to build a line from Oamaru to Naseby , and in 1877 an invitation was extended to the Waimate County Council to partake in a plan to connect Waimate to the Oamaru-Naseby line in either Duntroon or Livingstone and thus establish
603-411: A larger yard, where these railcars are sorted and dispatched in larger trains with other cars destined to similar locations. Because industrial spurs generally have less capacity and traffic than a mainline, they tend to have lower maintenance and signaling (train control) standards. Before the rise of the long-distance trucking in the early 1930s, railroads were the primary means of transportation around

The term "grain-dependent branch lines" began being used as early as 1978 to refer to the special case of these branch lines in agricultural areas whose viability depended on the economics of grain transport. The Western Grain Transportation Act of 1983 addressed this case specifically, but
1005-415: A tender was used with a narrow-gauge locomotive it usually carried only fuel, with water carried in the locomotive's tanks. The tender offered greater fuel capacity than a bunker on the locomotive and often the water capacity could be increased by converting redundant bunker space into a water tank. Large side tank engines might also have an additional rear tank (under the coal bunker), or a well tank (between

A deputation representing the advocates of the Oamaru-Naseby line made a presentation before the Waimate County Council on 12 July 1877, but the Council did not view the proposal as desirable. The Oamaru-Naseby proposal itself failed to come to fruition, with Duntroon ultimately served by the Kurow Branch and Livingstone located near the terminus of
1139-425: A variety of main line and industrial roles, particularly those involving shorter journeys or frequent changes in direction. There are a number of types of tank locomotive, based on the location and style of the water tanks. Side tanks are cuboid -shaped tanks which are situated on both sides of the boiler , extending all or part of the boiler's length. The tank sides extend down to the running platform, if such
1206-460: A wing tank and an inverted saddle tank. The inverted saddle tank was a variation of the Wing Tank where the two tanks were joined underneath the smokebox and supported it. This rare design was used for the same reasons as the wing tank but provided slightly greater water capacity. The Brill Tramway locomotive Wotton is believed to have had an inverted saddle tank. The inverted saddle tank
1273-527: Is a 4-4-0 American-type with wheels reversed. Wing tanks are side tanks that run the length of the smokebox, instead of the full length of the boiler. In the early 19th century the term "wing tank" was sometimes used as a synonym for side tank. Wing tanks were mainly used on narrow gauge industrial locomotives that could be frequently re-filled with water and where side or saddle tanks would restrict access to valve gear. The Kerry Tramway 's locomotive Excelsior has been described, by various sources, as both
1340-556: Is a type of secondary track used by railroads to allow customers at a location to load and unload railcars without interfering with other railroad operations. Industrial spurs can vary greatly in length and railcar capacity depending on the requirements of the customer the spur is serving. In heavily industrialized areas, it is not uncommon for one industrial spur to have multiple sidings to several different customers. Typically, spurs are serviced by local trains responsible for collecting small numbers of railcars and delivering them to

The length of side tanks was often limited in order to give access to the valve gear (inside motion). Tanks that ran the full length of the boiler provided greater water capacity and, in this case, cut-outs in the rectangular tank gave access to the valve gear. Longer side tanks were sometimes tapered downwards at
1541-532: The Bay of Plenty Region , lines were built inland to provide rail access to large logging operations. Today, many of the branch lines have been closed, including almost all of the general-purpose country lines. Those that remain serve ports or industries far from main lines such as coal mines, logging operations, large dairying factories, and steelworks . In Auckland and Wellington , two branch lines in each city exist solely for commuter passenger trains. For more, see

The Long Island Rail Road also refers to its services as "branches". In Chile, there are a lot of branch lines on its main line, of only a few remain operational. Most only operating in turistic services (like the Antilhue-Valdivia branch line), others have been taken over by other railways (like

There are several other specialised types of steam locomotive which carry their own fuel but which are usually categorised for different reasons. A Garratt locomotive is articulated in three parts. The boiler is mounted on the centre frame without wheels, and two sets of driving wheels (4 cylinders total) carrying fuel bunkers and water tanks are mounted on separate frames, one on each end of

2144-780: The German Class 61 and the Hungarian Class 242 . The contractor's locomotive was a small tank locomotive specially adapted for use by civil engineering contractor firms engaged in the building of railways. The locomotives would be used for hauling men, equipment and building materials over temporary railway networks built at the worksite that were frequently re-laid or taken up and moved elsewhere as building work progressed. Contractor's locomotives were usually saddle or well tank types (see above) but required several adaptations to make them suitable for their task. They were built to be as light as possible so they could run over

Some method of keeping mud and dust from clogging the wheels and brake shoes was also required – this either took the form of scraper bars fitted to the leading edge of the wheels or wheel washer jets supplied from the water tank. To handle long trains of loose-coupled (and often un-sprung) wagons, contractor's locomotives usually had very effective steam-powered brakes. Most lacked

Because tank locomotives are capable of running equally fast in both directions (see below) they usually have symmetrical wheel arrangements to ensure the same ride and stability characteristics regardless of the direction travelled, producing arrangements with only driving wheels (e.g. 0-4-0 T and 0-6-0 T ) or equal numbers of leading and trailing wheels (e.g. 2-4-2 T and 4-6-4 T ). However other requirements, such as
