Rule 55
Rule 55 was an operating rule which applied on British railways in the 19th and 20th centuries. It was superseded by the modular rulebook following re- privatisation of the railways. It survives, very differently named: the driver of a train waiting at a signal on a running line must remind the signaller of its presence. Rule 55 was introduced following a spate of accidents caused by signalmen forgetting that trains were standing on a running line, sometimes within sight of their signal boxes. It required that, if a train was brought to a stand at a signal, within three minutes in clear weather or immediately in rain, snow, or fog, the driver of the train must despatch his fireman, guard, or any shunter riding on the train, to the signal box to ensure that the signalman was aware of the presence of the train, and that all safeguards to protect it, such as slides or collars on the signal levers, were in place, the crewman then signing the train register to confirm this.

History Of Rail Transport In Great Britain
:''This article is part of the history of rail transport by country series.'' The Rail transport in Great Britain, railway system of Great Britain started with the building of local isolated wooden wagonways starting in the 1560s. A patchwork of local rail links operated by small private railway companies developed in the late 18th century. These isolated links expanded during the Railway Mania, railway boom of the 1840s into a national network, although still run by dozens of competing companies. Over the course of the 19th and early 20th centuries, these amalgamated or were bought by competitors until only a handful of larger companies remained (see railway mania). The entire network was brought under government control during the First World War and a number of advantages of amalgamation and planning were demonstrated. However, the government resisted calls for the nationalization, nationalisation of the network. In 1923, almost all the remaining companies were Railways Act 19 ...

Winwick Rail Crash
The Winwick rail crash took place at Winwick Junction, near Warrington on the London, Midland and Scottish Railway, on 28 September 1934. Two trains collided, resulting in 11 deaths and 19 injured. Background Although the signalman on duty was ultimately responsible for the collision, there were several contributing factors. The layout of the section was complex, with four running lines and a junction between the main Warrington-Preston line and the Warrington-Earlestown branch line. Those two lines carried so much traffic that the signalman had a booking lad with him in the signal box, whose function was to keep the train register and use it to remind the signalman of the position of trains within the section at any time. Sequence of events Shortly after 9pm a local train from Warrington, destined for Wigan and drawn by 2-4-2 tank engine No. 6632, entered the section. It was due to be turned off onto the Earlestown branch line, but Signalman Bloor at the Winwick J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GSM-R
GSM-R, Global System for Mobile Communications – Railway or GSM-Railway is an international wireless communications standard for railway communication and applications. A sub-system of European Rail Traffic Management System (ERTMS), it is used for communication between train and railway regulation control centers. The system is based on GSM and ''EIRENE – MORANE'' specifications which guarantee performance at speeds up to 500 km/h (310 mph), without any communication loss. GSM-R could be supplanted by LTE-R, with the first production implementation being in South Korea. However, LTE is generally considered to be a " 4G" protocol, and the UIC's Future Railway Mobile Communication System (FRMCS) program is considering moving to something " 5G"-based (specifically 3GPP R15/16), thus skipping two technological generations. History GSM-R is built on GSM technology, and benefits from the economies of scale of its GSM technology heritage, aiming at being a cos ...

Cab Secure Radio
Cab Secure Radio (CSR) was an in-cab analog transmission, analogue radiotelephone system formerly used on parts of the Rail transport in Great Britain, British railway network. Its main function was to provide a secure communication, secure speech link between the train driver and the Signalman (rail), signaller which could not be overheard by other train drivers. In areas where CSR was used, it had to be the primary method of communication between driver and signaller, always being used in preference to the ''signal post telephone''. CSR was replaced by the GSM-R Digital data, digital system, forming the initial phase of rollout of European Rail Traffic Management System, ERTMS throughout the UK. History CSR was first introduced in the Glasgow area in 1986 to enable driver-only operation of trains. It was later used in the London and Liverpool areas. In the Railway rule book, there is provision for a driver stopped at a red signal to disembark the train and access a track-sid ...

Railway Signalling
Railway signalling (), also called railroad signaling (), 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. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safeworking'' (Aus.). Not all these methods require the u ... [...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 usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Passed At Danger
A signal passed at danger (SPAD), known in the United States as a stop signal overrun and in Canada as passing a stop signal, is an event on a railway where a train passes a stop signal without authority. In the United States and Canada, this may be known colloquially as '' running a red'', though this idiom principally refers to automobiles passing red traffic signals. The name derives from red colour light signals and horizontal semaphore signals in the United Kingdom, which are said to be ''at danger'' when they indicate that trains must stop (also known as the signal being ''on''). This terminology is not used in North America where not all red signals indicate stop. In the UK, the alternative description signal passed at red (S.P.A.R.) is used where a signal changes to red in front of a train due to either a technical fault or in an emergency, such that the train is unable to stop before passing the signal despite being driven correctly. Causes Because of its high inert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castlecary Rail Accidents
Two rail accidents have occurred near Castlecary, Scotland. One of these was in 1937 and one in 1968. Both events involved rear-end collisions, and caused the deaths of 35 and 2 people respectively. 1937 accident On 10 December 1937 at 4:37 pm, the 4:03 pm Edinburgh Waverley to Glasgow Queen Street express train collided at Castlecary station with the late-running 2:00 pm express train from Dundee to Glasgow Queen Street on the Edinburgh to Glasgow main line of the London and North Eastern Railway (LNER), killing 35 people. At the time of the accident, whiteout conditions prevailed due to a snowstorm. The Edinburgh train hit the rear of the standing Dundee train at an estimated . Due to the confines of the location, the rear four coaches of the Dundee train disintegrated completely. The engine of the Dundee train, an LNER Class D29 no. 9896 ''Dandie Dinmont'', was pushed forward with the brakes on. The locomotive of the Edinburgh train, LNER Class A3 no. 2744 ''Grand P ...

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent dispatchers and operators from causing accidents, both by info ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond Sign
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privatisation Of British Rail
The privatisation of British Rail was the process by which ownership and operation of the railways of Great Britain passed from government control into private hands. Begun in 1994, it had been completed by 1997. The deregulation of the industry was initiated by EU Directive 91/440 in 1991, which aimed to create a more efficient rail network by creating greater competition. British Railways (BR) had been in state ownership since 1948, under the control of the British Railways Board (BRB). Under the Conservative government of Margaret Thatcher elected in 1979, various state-owned businesses were sold off, including various functions related to the railways – Sealink ferries and British Transport Hotels by 1984, Travellers Fare catering by 1988 and British Rail Engineering Limited (train building) by 1989. It was under Thatcher's successor John Major that the railways themselves were privatised, using the Railways Act 1993. The operations of the BRB were broken up and sold ...
