A block post in railway signalling is the signal box at one end of a block section. [1]
In Germany, block posts are known as Blockstellen (abbreviation: Bk) and are defined as railway facilities on the open line that mark the end of a block section, as part of a block system. They usually have a home signal in each direction and on each running line. They are mainly found where the distance between two railway stations is greater than average.
In the early years of the railway, block posts were local signal boxes manned with block post keepers. Today there are only a few of these classic, railway staff-operated block posts. Their function has been largely superseded by equipment that forms part of an automatic block signalling (Selbsttätiger Streckenblock or Sbk) system or by a central block post in a station signal box at one end of the section between two stations.
Block posts are described in the German railway regulations, the Eisenbahn-Bau- und Betriebsordnung or EBO, at § 4 sub-paragraph 4. [2]
On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable. Signalling control was originally exercised via a decentralised network of control points that were known by a variety of names including signal box, interlocking tower and signal cabin. Currently these decentralised systems are being consolidated into wide scale signalling centres or dispatch offices. Whatever the form, signalling control provides an interface between the human signal operator and the lineside signalling equipment. The technical apparatus used to control switches (points), signals and block systems is called interlocking.
Railway signalling (BE), also called railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year.
Rail terminology is a form of technical terminology. The difference between the American term railroad and the international term railway is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist.
The Watercress Line is the marketing name of the Mid-Hants Railway, a heritage railway in Hampshire, England, running 10 miles (16 km) from New Alresford to Alton where it connects to the National Rail network. The line gained its popular name in the days when it was used to transport locally grown watercress to markets in London. The railway currently operates regular scheduled services, along with dining trains, real ale trains and numerous special events throughout the year.
In railway signalling, a token is a physical object which a train driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the names of the section to which it belongs. A token system is more commonly used for single lines because of the greater risk of collision in the event of a mistake being made by a signaller or traincrew, than on double lines.
The Lilydale line is a commuter railway line in the city of Melbourne, Victoria, Australia. Operated by Metro Trains Melbourne, it is the city's sixth-longest metropolitan railway line at 37.8 kilometres (23.5 mi). The line runs from Flinders Street station in central Melbourne to Lilydale station in the east, serving 27 stations via Burnley, Box Hill, Ringwood, and Croydon. The line operates for approximately 19 hours a day with 24 hour service available on Friday and Saturday nights. During peak hours, headways of up to 15 minutes are operated, with services every 20–30 minutes during off-peak hours. Trains on the Lilydale line run in two three-car formations of X'Trapolis 100 trainsets.
The East Rail line is one of the ten lines that form MTR, the mass transit system in Hong Kong. The railway line starts at Lo Wu or Lok Ma Chau, both of which are boundary crossing points into Shenzhen and joins in the north at Sheung Shui to terminate at Admiralty station on Hong Kong Island. At approximately 45.8 km (28.5 mi), the line is the second longest line within the network, behind the Tuen Ma line. The line's colour is light blue.
South Geelong railway station is located on the Warrnambool line in Victoria, Australia. It serves the southern Geelong suburb of South Geelong, and it opened on 1 November 1883.
Strathfield railway station is a heritage-listed railway station located on the Main Suburban line in the Sydney suburb of Strathfield in the Municipality of Strathfield local government area of New South Wales, Australia. The station is served by Sydney Trains T1 North Shore & Western Line, T9 Northern Line and T2 Inner West & Leppington Line suburban services as well as NSW TrainLink Intercity and regional services. The station is located on the Main Northern and Main Western railway lines, forming a major junction for regional and suburban rail services. The station and associated infrastructure was added to the New South Wales State Heritage Register on 2 April 1999.
Linienzugbeeinflussung is a cab signalling and train protection system used on selected German and Austrian railway lines as well as on the AVE and some commuter rail lines in Spain. The system was mandatory where trains were allowed to exceed speeds of 160 km/h (99 mph) in Germany and 220 km/h (140 mph) in Spain. It is also used on some slower railway and urban rapid transit lines to increase capacity. The German Linienzugbeeinflussung translates to continuous train control, literally: linear train influencing. It is also called linienförmige Zugbeeinflussung.
Absolute block signalling is a British signalling block system designed to ensure the safe operation of a railway by allowing only one train to occupy a defined section of track (block) at a time. Each block section is manually controlled by a signalman, who communicates with the other block sections via telegraph. This system was used on double or multiple lines where use of each line is assigned a direction of travel before the introduction of track circuits, and is still used on lines which lack track circuiting.
Australian railway signalling varies between the States of Australia, because the individual States are responsible for the railway systems within their own borders, with, historically, no need to co-ordinate between states except at the boundaries.
Hamilton railway station is a heritage-listed railway station on the Newcastle line in the inner Newcastle suburb of Hamilton in New South Wales, Australia. It was added to the New South Wales State Heritage Register on 2 April 1999.
Transmission Voie-Machine is a form of in-cab signalling originally deployed in France and is mainly used on high-speed railway lines. TVM-300 was the first version, followed by TVM-430.
The railways in Germany use several abbreviations to differentiate between various types of stations, stops, railway facilities and other places of rail service.
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.
Railway semaphore signal is one of the earliest forms of fixed railway signals. This semaphore system involves signals that display their different indications to train drivers by changing the angle of inclination of a pivoted 'arm'. Semaphore signals were patented in the early 1840s by Joseph James Stevens, and soon became the most widely used form of mechanical signal. Designs have altered over the intervening years, and colour light signals have replaced semaphore signals in most countries, but in a few they remain in use.
The current French railway signalling system is in force on the Réseau Ferré de France since 1930, when the code Verlant was applied.
The first railway signalling in Greece was installed on the Athens–Piraeus Railway at the turn of the 20th century, when semaphores and boards were added with the line's electrification. Other Greek trains at that time were controlled by signals given manually by station masters. During World War II, German occupation forces installed mechanically operated semaphore signals at the entrance to all stations, with some light signals at busy stations. Modern signalling is provided through colour light signals. Radio communication between train stations and drivers was introduced in 1973 and digital communication is an ongoing present-day introduction.
The Rosenheim–Salzburg railway is a continuous double track and electrified main line railway almost entirely within the German state of Bavaria. It is an international transport corridor, linking Rosenheim to Salzburg in Austria.
