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.
In railroad structures, and rail terminology, a wye or triangular junction is a triangular joining arrangement of three rail lines with a railroad switch at each corner connecting to the incoming lines. A turning wye is a specific case.
The East Coast Main Line (ECML) is a 393-mile long (632 km) electrified railway between its southern terminus at London King's Cross station and Edinburgh Waverley via Peterborough, Doncaster, York, Darlington, Durham and Newcastle. The line is a key transport artery on the eastern side of Great Britain running broadly parallel to the A1 road. The main line acts as a 'spine' for several diverging branches, serving destinations such as Cambridge, Leeds, Hull, Sunderland and Lincoln, all with direct services to London. In addition, a few ECML services extend beyond Edinburgh to serve Glasgow Central, although the principal London-Glasgow route is the West Coast Main Line (WCML).
Rail transport operations are the day-to-day operations of a railway. A railway has two major components: the infrastructure and the rolling stock
The London, Tilbury and Southend line, also known as Essex Thameside, is a commuter railway line on the British railway system. It connects Fenchurch Street station, in central London, with destinations in east London and Essex, including Barking, Upminster, Basildon, Grays, Tilbury, Southend and Shoeburyness.
The Wisbech and March line is a railway line between March and Wisbech in Cambridgeshire, England. A number of proposals are currently being investigated relating to the possible restoration of passenger services along the route.
The Cambrian Line, sometimes split into the Cambrian Main Line and Cambrian Coast Line for its branches, is a railway line that runs from Shrewsbury, England, westwards to Aberystwyth and Pwllheli in Wales. Passenger train services are operated by Transport for Wales Rail between the western terminals of Pwllheli, in Gwynedd, and Aberystwyth, in Ceredigion, and the eastern terminal at Shrewsbury, Shropshire, as part of the Wales & Borders franchise. The railway line is widely regarded as scenic, as it passes through the Cambrian Mountains in central Wales, and along the coast of Cardigan Bay in Snowdonia National Park.
Gauntlet track or interlaced track is an arrangement in which railway tracks run parallel on a single track bed and are interlaced in such a way that only one pair of rails can be used at any time. Since this requires only slightly more width than a single track, all rails can be carried on the same crossties/sleepers. Trains run on the discrete pair of rails appropriate to their direction, track gauge or loading gauge.
Exeter Central railway station is the most central of the stations in the city of Exeter, Devon, United Kingdom. It is 171 miles 30 chains (275.8 km) down the line from London Waterloo. The station is smaller than Exeter St Davids on the west side of the city. Great Western Railway manages the station and operates most services, with South Western Railway providing the rest.
Rail transport – means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks consisting of steel rails installed on sleepers/ties and ballast.
Templecombe railway station serves the town of Templecombe in Somerset, England. It is situated on the West of England Main Line, 112 miles 2 chains (180.3 km) down the line from London Waterloo. The main station opened in 1860 but a smaller station on the lower line opened in 1862. It was closed in 1966 but was reopened in 1983 following local community pressure. It is currently operated by South Western Railway.
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.
Doncaster PSB is a signalling centre on the East Coast Main Line (ECML) railway in the United Kingdom, principally covering the line from London to Edinburgh but also encompassing other lines diverging and converging to the ECML.
The East Coast Main Line Route Utilisation Strategy (RUS), published by Network Rail in February 2008, was the seventh RUS.
The application of railway signals on a rail layout is determined by various factors, principally the location of points of potential conflict, as well as the speed and frequency of trains and the movements they require to make.
France has a large network of high-speed rail lines. As of June 2021, the French high-speed rail network comprises 2,800 km (1,740 mi) of tracks, making it one of the largest in Europe and the world. As of early 2023, new lines are being constructed or planned. The first French high-speed railway, the LGV Sud-Est, linking the suburbs of Paris and Lyon, opened in 1981 and was at that time the only high-speed rail line in Europe.
A train station, railroad station, or railroad depot and railway station is a railway facility where trains stop to load or unload passengers, freight, or both. It generally consists of at least one platform, one track, and a station building providing such ancillary services as ticket sales, waiting rooms, and baggage/freight service. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements.
The Reading–Taunton line is a major branch of the Great Western Main Line from which it diverges at Reading railway station. It runs to Cogload Junction where it joins the Bristol to Exeter and Penzance line.
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros are able to reduce headways while maintaining or even improving safety.
Route capacity is the maximum number of vehicles, people, or amount of freight than can travel a given route in a given amount of time, usually an hour. It may be limited by the worst bottleneck in the system, such as a stretch of road with fewer lanes. Air traffic route capacity is affected by weather. For a metro or a light rail system, route capacity is generally the capacity of each vehicle, times the number of vehicles per train, times the number of trains per hour (tph). In this way, route capacity is highly dependent on headway. Beyond this mathematical theory, capacity may be influenced by other factors such as slow zones, single-tracked areas, and infrastructure limitations, e.g. to useful train lengths.
