Merri Railway Station
Merri railway station is located on the Mernda railway line, Mernda line in Victoria (Australia), Victoria, Australia. It serves the north-eastern Melbourne suburb of Northcote, Victoria, Northcote, and it opened on 8 October 1889 as Northcote. It was renamed Merri on 10 December 1906. History Merri station opened on 8 October 1889, when the Inner Circle railway line, Inner Circle line was extended from North Fitzroy railway station, North Fitzroy to Reservoir railway station, Reservoir. The original conception of the station was to act as a major Junction (rail), junction in a planned ''"North Suburban Railway System''. ''The Argus (Melbourne), The Argus'' reported in 1887 that; "The Station at Union-street, as shown on our plan, must necessarily be the most important in the Northern System, as lines branch from this point to Preston and Whittlesea on the north ; Heidelberg, Kew, &.c., on the east; Carlton, Royal-park, North Melbourne, and Spencer-street on the south-west; Fit ...

Public Transport Victoria
Public Transport Victoria (PTV) is the brand name for public transport in the Australian state of Victoria. It was the trading name of the Go Public Transport Development Authority (PTDA), a now-defunct statutory authority in Victoria, responsible for providing, coordinating, and promoting public transport. The PTV began operating on 2 April 2012, taking over many of the responsibilities previously exercised by the Director of Public Transport and the Department of Transport. It also took over the marketing of public transport in Victoria from Metlink and Viclink, as well as responsibility for the myki ticketing system, formerly handled by the Transport Ticketing Authority. PTV's functions were transferred to the Department of Transport on 1 July 2019. However, PTV continues to exist as the brand for public transport services in Victoria. Governance PTV is the trading name of the Public Transport Development Authority (PTDA). The PTDA was established by the ''Transport Leg ...

North Fitzroy Railway Station
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Line Automatic Signalling
Double Line Automatic Signalling is a form of railway signalling used on the majority of double line 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 li ... sections in New Zealand. Double Line Automatic Signalling uses track circuits to detect the presence of trains in sections broken up by intermediate signals. Usually there is an 'up' and a 'down' main line, and beyond station limits the lines are not bi-directionally signalled. DLAS is not designed for wrong-line running in emergency situations.{{Cite web , url=https://www.taic.org.nz/inquiry/ro-2008-110 , title=Report 08-110 train control operating irregularity leading to potential low-speed, head-on collision Amokura 23 September 2008 , access-date=28 November 2020 Junctions or points At junctions or points, one of or both main ...

Northcote Railway Station
Northcote railway station is located on the Mernda line in Victoria, Australia. It serves the north-eastern Melbourne suburb of Northcote, and opened on 8 October 1889 as Middle Northcote. It was renamed Northcote on 10 December 1906. History Northcote station opened on 8 October 1889, when the Inner Circle line was extended from North Fitzroy to Reservoir. Like the suburb itself, the station is believed to be named after Stafford Henry Northcote, who was British Chancellor of the Exchequer between 1874 and 1880, Foreign Secretary between 1885 and 1886, and a co-author of the Northcote–Trevelyan Report in 1853. In 1973, both platforms were extended at the down end of the station. In 1986, the former goods sidings, located at the down end of the station, were abolished. A crossover, also located at the down end, was spiked out of use around that time, and was removed at a later date. During October 1987, the double line block system between Northcote – Merri and No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signalling Block System
Signalling block systems enable the safe and efficient operation of railways by preventing collisions between trains. The basic principle is that a track is broken up into a series of sections or "blocks". Only one train may occupy a block at a time, and the blocks are sized to allow a train to stop within them. That ensures that a train always has time to stop before getting dangerously close to another train on the same line. The block system is referred to in the UK as the ''method of working'', in the US as the ''method of operation'', and in Australia as ''safeworking''. In most situations, a system of signals is used to control the passage of trains between the blocks. When a train enters a block, signals at both ends change to indicate that the block is occupied, typically using red lamps or indicator flags. When a train first enters a block, the rear of the same train has not yet left the previous block, so both blocks are marked as occupied. That ensures there is sligh ...

Rail Directions
Railroad directions are used to describe train directions on rail systems. The terms used may be derived from such sources as compass directions, altitude directions, or other directions. However, the railroad directions frequently vary from the actual directions, so that, for example, a "northbound" train may really be headed west over some segments of its trip, or a train going "down" may actually be increasing its elevation. Railroad directions are often specific to system, country, or region. Radial directions Many rail systems use the concept of a center (usually a major city) to define rail directions. Up and down In British practice, railway directions are usually described as "up" and "down", with "up" being towards a major location. This convention is applied not only to the trains and the tracks, but also to items of lineside equipment and to areas near a track. Since British trains run on the left, the "up" side of a line is usually on the left when proceeding in the "u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Railway Historical Society
The Australian Railway Historical Society (ARHS) aims to foster an interest in the railways, and record and preserve many facets of railway operations. It had divisions in every state and the Australian Capital Territory, although the ACT division was wound up in 2016, along with the Victorian division in 2020. Since 1967, when each division incorporated, the state divisions have operated as separate entities. Each still trades under the ARHS brand, except in Western Australia, where the division is called Rail Heritage WA. Individual membership exceeds 2,500. Background The ARHS was founded in Sydney in 1933 as The Railway Circle, becoming the Australasian Railway and Locomotive Historical Society shortly afterwards. The society's name was changed to the present form in 1952. Divisions were later formed in most states, most of which established a railway museum, namely: *ACT - Canberra Railway Museum, Kingston *Queensland - Rosewood Railway Museum *South Australia - SteamR ...

Boom Barrier
A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counterweighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions. Some boom gates also have a second arm which hangs 300 to 400 mm below the upper arm when lowered, to increase approach visibility, and which hangs on links so it lies flat with the main boom as the barrier is raised. Some barriers also feature a pivot roughly half way, where as the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down ''L'' when raised. Automatic boom barrier There are various technologies for an automatic boom barrier. One of them is electro-mechanical, which is widely used due to its reliability. The ...

Signal Box
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The '' IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interlocking
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. The signalling appliances and 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 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 minimal interlocking consists of signals, but usuall ... [...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 ...
