Passing Loop
A passing loop (UK usage) or passing siding (North America) (also called a crossing loop, crossing place, refuge loop or, colloquially, a hole) is a place on a single line railway or tramway, often located at or near a station, where trains or trams travelling in opposite directions can pass each other. Trains/trams going in the same direction can also overtake, provided that the signalling arrangement allows it. A passing loop is double-ended and connected to the main track at both ends, though a dead end siding known as a refuge siding, which is much less convenient, can be used. A similar arrangement is used on the gauntlet track of cable railways and funiculars, and in passing places on single-track roads. Ideally, the loop should be longer than all trains needing to cross at that point. Unless the loop is of sufficient length to be dynamic, the first train to arrive must stop or move very slowly, while the second to arrive may pass at speed. If one train is too lo ...

Forres Railway Station, Moray (geograph 6260345)
Forres (; ) is a town and former royal burgh in the north of Scotland on the Moray coast, approximately northeast of Inverness and west of Elgin. Forres has been a winner of the Scotland in Bloom award on several occasions. There are many geographical and historical attractions nearby such as the River Findhorn, and there are also classical, historical artifacts and monuments within the town itself, such as Forres Tolbooth and Nelson's Tower. Brodie Castle, the home of the Brodie Clan, lies to the west of the town, close to the A96. Pre-history and archaeology Between 2002 and 2013 some 70 hectares of land was investigated by archaeologists in advance of a proposed residential development on the southern fringes of the town. They found an extensive Iron Age settlement and evidence that people lived in the area from the Neolithic (radiocarbon dates from the 4th to the mid-3rd millennium BC were found) to the Early Historic period (they found radiocarbon dates from the 9th–12 ...

Side Platforms
A side platform (also known as a marginal platform or a single-face platform) is a railway platform, platform positioned to the side of one or more railway tracks or guideways at a railway station, tram stop, or bus rapid transit, transitway. A station having dual side platforms, one for each direction of travel, is the basic design used for double-track railway lines (as opposed to, for instance, the island platform where a single platform lies between the tracks). Side platforms may result in a wider overall footprint for the station compared with an island platform, where a single width of platform can be shared by riders using either track. In some stations, the two side platforms are connected by a footbridge or Subway (crossing), tunnel to allow safe access to the alternate platform. While a pair of side platforms is often provided on a dual-track line, a single side platform is usually sufficient (trains are usually only boarded from one side) for a single-track line. Layou ...

Right- And Left-hand Traffic
Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side or to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the '' rule of the road''. The terms right- and left-hand ''drive'' refer to the position of the driver and the steering wheel in the vehicle and are, in automobiles, the reverse of the terms right- and left-hand ''traffic''. The rule also includes where on the road a vehicle is to be driven, if there is room for more than one vehicle in one direction, and the side on which the vehicle in the rear overtakes the one in the front. For example, a driver in an LHT country would typically overtake on the right of the vehicle being overtaken. RHT is used in 165 countries and territories, mainly in the Americas, Continental Europe, most of Africa and mainland Asia (except South Asia and Thailand), while 75 countries use LHT, which account for about a ...

Multiplicative Inverse
In mathematics, a multiplicative inverse or reciprocal for a number ''x'', denoted by 1/''x'' or ''x''−1, is a number which when Multiplication, multiplied by ''x'' yields the multiplicative identity, 1. The multiplicative inverse of a rational number, fraction ''a''/''b'' is ''b''/''a''. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the Function (mathematics), function ''f''(''x'') that maps ''x'' to 1/''x'', is one of the simplest examples of a function which is its own inverse (an Involution (mathematics), involution). Multiplying by a number is the same as Division (mathematics), dividing by its reciprocal and vice versa. For example, multiplication by 4/5 (or 0.8) will give the same result as division by 5/4 (or 1.25). Therefore, multiplication by a number followed by multiplication by its reciprocal yie ...

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on a block of rail tracks to control railway signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent dispatchers and operators from causing accidents, both by informin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Rail Track Corporation
The Australian Rail Track Corporation (ARTC) is an Australian Government-owned statutory corporation. It operates one of the largest rail networks in the nation, spanning across five states and 39 worksites. ARTC continues to expand the network through major infrastructure projects including Inland Rail, which is a new freight line between Melbourne and Brisbane via regional Victoria, NSW and Queensland that will complete Australia’s national freight network and better connect producers to markets. History In November 1996, the Australian Government announced a major rail reform package that included the sale of government-owned train operators Australian National and National Rail, and the establishment of ARTC to manage the sections of the interstate rail network which had been controlled by the two former organisations. ARTC was incorporated in February 1998, with operations starting in July 1998 when the lines managed by Australian National's Track Australia were tran ...

Catch Points
Catch points and trap points are types of railroad switch, points which act as railway safety devices. Both work by guiding railroad car, railway carriages and trucks from a dangerous route onto a separate, safer track. Catch points are used to derailment, derail vehicles which are out of control (known as Runaway train, ''runaways'') on steep slopes. Trap points are used to protect rail terminology#M, main railway lines from unauthorised vehicles, moving onto them from rail siding, sidings or branch lines. Either of these track arrangements may lead the vehicles into a sand drag or safety siding, track arrangements which are used to safely stop them after they have left the main tracks. A derail is another device used for the same purposes as catch and trap points. Trap points ''Trap points'' are found at the exit from a rail siding, siding or where a secondary track joins a main line. A facing and trailing, facing turnout is used to prevent any unauthorised movement that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
