Dual-gauge
In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway lines is the number of rails in place. However, it is sometimes necessary for track to carry railway vehicles with wheels matched to two different gauges. Such track is described as dual gauge – achieved either by addition of a third rail, if it will fit, or by two additional rails. Dual-gauge tracks are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks. It is therefore usual to build dual-gauge or other multi-gauge tracks only when necessitated by lack of space or when tracks of two different gauges meet in marshalling yards or passenger stations. Dual-gauge tracks are by far the most common configuration, but triple-gauge tracks have been built in some situations. Background The rail gauge is the most fundamental specification of a railway.

Railroad Switch
A railroad switch (), turnout, or ''set ofpoints () is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off. The most common type of switch consists of a pair of linked tapering rails, known as ''points'' (''switch rails'' or ''point blades''), lying between the diverging outer rails (the ''stock rails''). These points can be moved laterally into one of two positions to direct a train coming from the point blades toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it will be directed to one of the two paths, depending on the position of the points) is said to be executing a ''facing-point movement''. For many types of switch, a train coming from either of the converging directions will pass through the switch regardless of the position of the points, as the vehicle's wheels will force the points to move ...

Wallaroo, South Australia
Wallaroo is a port town on the western side of Yorke Peninsula in South Australia, northwest of Adelaide. It is one of the three Copper Triangle towns famed for their historic shared copper mining industry, and known together as "Little Cornwall", the other two being Kadina, about to the east, and Moonta, about south. In 2016, Wallaroo had a population of 3,988 according to the census held. Description Wallaroo is about north of Moonta and west of Kadina. Since 1999, the rural broadacre farming area to the north of the town has been officially known as Wallaroo Plain The area south of Wallaroo is Warburto. The Warburto railway station name was derived from the Narungga name for a nearby spring. History Aboriginal The Narungga are the group of Indigenous Australians whose traditional lands include what is now termed Yorke Peninsula in South Australia. The name "Wallaroo" comes from the Aboriginal word ''wadlu waru'', meaning wallaby urine. The early settlers tried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A '' loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A '' structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wheelset (rail Transport)
A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle such that both wheels rotate in unison. Wheelsets are often mounted in a bogie ("truck" in North America) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle. Most modern freight cars and passenger cars have bogies each with two wheelsets, but three wheelsets (or more) are used in bogies of freight cars that carry heavy loads, and three-wheelset bogies are under some passenger cars. Four-wheeled goods wagons that were once near-universal in Europe and Great Britain and their colonies have only two wheelsets; in recent decades such vehicles have become less common as trainloads have become heavier. Conical wheel-tread Most train wheels have a conical taper of about 1 in 20 to enable the wheelset to follow curves with less chance of the wheel flanges coming in contact with the rail sides, and to reduce curve resistance.

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/ Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met †... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Ft And 1520 Mm Gauge Railways
Railways with a railway track gauge of first appeared in the United Kingdom and the United States. This gauge became commonly known as Russian gauge because the government of the Russian Empire later chose it in 1843 — former areas of the Empire have inherited this standard. In 1970 Soviet Railways re-defined the gauge as 1,520 mm (). With about of track, Russian gauge is the second-most common gauge in the world, after . History Great Britain, 1748 In 1748, the Wylam waggonway was built to a gauge for the shipment of coal from Wylam to Lemington down the River Tyne. In 1839, the Eastern Counties Railway was constructed; and in 1840, the Northern and Eastern Railway was built. In 1844, both lines were converted to . In 1903, the East Hill Cliff Railway, a funicular, was opened. United States, 1827 In 1827, Horatio Allen, the chief engineer of the South Carolina Canal and Rail Road Company, prescribed the usage of gauge and many other railroads in Sou ...
