Facing And Trailing
Facing or trailing are railway turnouts (or 'points' in the UK) in respect to whether they are divergent or convergent. When a train traverses a turnout in a facing direction, it may diverge onto either of the two routes. When travelled in a trailing direction, the two routes converge onto each other. History In the early history of railways in Britain, when signalling and interlocking were primitive, and staff were inexperienced, facing turnouts were a hazard, because a train travelling at high speed could be accidentally switched into a slow speed divergence or dead end. Facing turnouts were therefore banned, except when absolutely necessary. However, facing turnouts cannot be avoided where there are crossing loops on single lines. With the widespread availability of electrically interlocked signalling in modern times, the rule against facing turnouts has been relaxed. Diamond crossings Fixed diamond crossings (with no moving parts) count as trailing points in both direc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

Interlocking
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junction (rail), junctions or crossings. The signalling appliances and Track (rail transport), tracks are sometimes collectively referred to as an ''interlocking plant''. An interlocking is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. Interlocking is a safety measure designed to prevent signals and Railroad switch, points/switches from being changed in an improper sequence. For example interlocking would prevent a signal from being changed to indicate a diverging route, unless the corresponding points/switches had been changed first. In North America, the official railroad definition of interlocking is: "''An arrangement of signals and signal appliances so interconnected that their movements must succeed each other in proper sequence''". Configuration and use A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossing 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 long for ...

Diamond Crossing
A double junction is a railway junction where a double-track railway splits into two double track lines. Usually, one line is the main line and carries traffic through the junction at normal speed, while the other track is a branch line that carries traffic through the junction at reduced speed. A number of configurations are possible. At grade Diamond The simplest and oldest arrangement consists of two turnouts (points) and a fixed Diamond crossing. Because the diamond needs to be relatively coarse, say 1 in 8, the curve radius is necessarily small, leading to a speed of perhaps . This type of junction is common on street-running tramways, where speeds are quite low and junction must fit into the available road space. Because the points are close together, the entire junction can be controlled by the mechanical point rodding of a single signal box. Signal passed at danger (SPAD) protection — A train from R to P with 12 points reverse is protected from a train from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breadalbane, New South Wales
Breadalbane () is a small village located in the Southern Tablelands of New South Wales, Australia in Upper Lachlan Shire. It is located on the Lachlan River headwaters and not far from Goulburn. At the , Breadalbane had a population of 107. Overview Located in the region known natively as "Mulwarry" to the native Wiradjuri people, it was renamed to Breadalbane Plains by Lachlan Macquarie in 1820 (although there is a reference to a Mr. Chisolm naming the location after his home in Scotland). This little town is also located near and adjacent to the major Hume Highway which links Sydney to Melbourne via an inland route. Previously the highway used to go through the small town however it was bypassed in 1993 as part of the Cullerin Range Deviation of the Hume Highway. Breadalbane Railway Station is also situated on the Main Southern Railway, the NSW portion of the Sydney–Melbourne rail line. The town was originally accessible via tracks arising from early settlement with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History It opened in 1875 as a crossing loop with a goods siding. The line was duplicated , and the goods siding was arranged so that it was connected to the main lines with trailing points. There were also refuge loops in both directions. In its final form, Jerrawa had an island platform between the two main lines and several goods sidings. The building on the platform was of timber construction, with corrugated iron roofing. It was closed to passenger services in 1975.

Woy Woy Railway Station
Woy Woy railway station is located on the Main Northern line in New South Wales, Australia. It serves the southern Central Coast suburb of Woy Woy opening on 1 February 1889. Platforms and services Woy Woy has one island platform with two faces. It is serviced by NSW TrainLink Central Coast & Newcastle Line services travelling from Sydney Central to Newcastle. Peak-hour services travel from Central to Wyong via the North Shore line. There are two crossovers south of the station, allowing trains to terminate in an emergency. They cannot be used for regular working as they are manually operated by levers next to the tracks and there are no signals to permit any movements over the points. All signals at this station are controlled from Cowan or Gosford.

Newbridge, New South Wales
Newbridge is a village of about 100 residents in New South Wales, Australia in Blayney Shire. It is approximately 30 km from Bathurst and 15 km from Blayney in the Central Tablelands of NSW. At the 2006 census 6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second small ..., Newbridge had a population of 90 people. History Newbridge village developed around the railway line and station which was built in 1876. The station was called ''Back Creek'', however, the post office which opened two months later in the same year was called ''Duramana''. To avoid confusion with Duramana on the other side of Bathurst and due to either the large number of Irish settlers in the area reflecting upon ''Newbridge'' in Ireland or as the result of the opening of a pedestrian overhead bridge built ...
