Sunbury Railway Line
The Sunbury railway line is a suburban electric railway in Melbourne, Australia. It has 15 stations, in Myki ticketing Zones 1 and 2. It is the electrified section of the Bendigo railway within metropolitan Melbourne. Prior to the line extension to Sunbury, the line was known as the Sydenham railway line, and prior to the extension of electrification to Sydenham, the line was known as the St Albans railway line. Description The Sunbury line generally traverses flat country and thus has no major earthworks, except on the west bank of the Maribyrnong River where it requires some moderately heavy earthworks. It has eight level crossings and several bridges under or over roads. Infrastructure The line is quadrupled to South Kensington railway station, then is double track for the rest of the line, although from South Kensington to Footscray, it runs alongside the Werribee line, effectively extending the quadruple track to there. The line is also paralleled by a double t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commuter Rail
Commuter rail, or suburban rail, is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Generally commuter rail systems are considered heavy rail, using electrified or diesel trains. Distance charges or zone pricing may be used. The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail. Similar non-English terms include ''Treno suburbano'' in Italian, '' Cercanías'' in Spanish, Aldiriak in Basque, Rodalia in Catalan/Valencian, Proximidades in Galician, '' Proastiakos'' in Greek, ''Train de banlieue'' in French, '' Banliyö treni '' in Turkish, ''Příměstský vlak'' or ''Esko'' in Czech, '' Elektrichka'' in Russian, ''Pociąg podmiejski '' in Polish and ''Pendeltåg'' in Swedish. Some services share similarities with both commuter rail and high-frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double Track
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side a ...

South Kensington Railway Station
South Kensington railway station is located on the Werribee and Williamstown lines in Victoria, Australia. It serves the inner north-western Melbourne suburb of Kensington, and it opened on 11 March 1891. Freight lines operate to the south of the station. The closest of these lines are used by V/Line to reverse empty trains from Traralgon and Bairnsdale services, while the tracks further south are used by a variety of standard gauge freight operators. The lines to the east join Melbourne Yard, while those to the west are the South Kensington–West Footscray set of lines that lead to either South Dynon or West Footscray, via the Bunbury Street tunnel. Private sidings that were formerly provided around South Kensington have now all closed. This included a siding to a large wool store to the north-east (now demolished), one to a warehouse and silos to the east (open but no longer served by rail), and two sidings to the north serving the Melbourne City Council abattoirs ...

Quadruple Track
A quadruple-track railway (also known as a four-track railway) is a railway line consisting of four parallel tracks with two tracks used in each direction. Quadruple-track railways can handle large amounts of traffic, and so are used on very busy routes or sections. Such conversion is referred to as "quadruplication". A railway line with six parallel tracks, or a sextuple-track railway, has three tracks in each direction. The corresponding term is "sextuplication". There are also instances of railway lines or sections with eight tracks, and cases with three or five tracks. Advantages * Quadruple track can carry a larger amount of traffic, with usually at least twice the capacity of double track. It is often seen around large metropolises or on busy inter-city corridors. * On quadruple track, faster trains can overtake slower ones, and so quadrupling help speed up trains. High-speed rail with 200 km/h average speed and commuter rail with 40 km/h average can co-exist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overpass
An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An ''overpass'' and ''underpass'' together form a grade separation. Stack interchanges are made up of several overpasses. History The world's first railroad flyover was constructed in 1843 by the London and Croydon Railway at Norwood Junction railway station to carry its atmospheric railway vehicles over the Brighton Main Line. Highway and road In North American usage, a ''flyover'' is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection. Traffic engineers usually refer to the latter as a '' grade separation''. A flyover may also be an extra ramp added to an existing interchange, either replacing an existing cloverleaf loop (or being built in place of one) with a higher, faster ramp that eventually bears left, but m ...

Underpass
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Level Crossing
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An ''overpass'' and ''underpass'' together form ... or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the locatio ...

Maribyrnong River
The Maribyrnong River is a perennial river of the Port Phillip catchment, located in the northwestern suburbs of Melbourne, in the Australian state of Victoria. Course The Maribyrnong River draws its headwaters from near Mount Macedon within the Macedon Ranges, part of the Great Dividing Range. Formed by the confluence of the Jackson Creek and the Deep Creek below , the river flows generally southward, joined by two minor tributaries before reaching its confluence with the Yarra River at , to eventually empty into Port Phillip. The river descends over its course. Headwaters The head of the Maribyrnong catchment is situated in the Macedon Ranges region of central Victoria around northwest of Melbourne City Centre. Various creeks beginning in the southern Mount Macedon area flow into Riddells Creek which in turn flows into the Jackson Creek. The Jackson Creek starts its journey northwest of Gisborne, north of Melbourne CBD. The other major tributary of the Maribyrno ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contac ...
