The last vehicle of a train is supposed to carry a red lamp at the rear. Earlier, the requirement was for merely an oil lamp, which was often missing or very feeble. In recent years provision of an electric lamp, as mandated by the rules, has become more common.

Last vehicle indications are of different types. A large 'X' is often seen painted on the rear of the coach that is the last one. A set of concentric circles may also be seen, although this seems to be going out of use as of 2008. EMU/DMU rakes have a smaller painted 'X' (red on white) at the rear, or sometimes a series of diagonal strokes painted on; these painted symbols are all in addition to the lamp mentioned above. In addition, a small board with 'LV' (black on yellow) is often attached to the rear of the vehicle (it stands for Last Vehicle).

If a train passes by a station or signal cabin without the appropriate last vehicle indication (or without confirmation of the number of coaches or wagons), it is assumed that the train has separated and suitable emergency procedures are brought into play.

There are some cases where a last vehicle indication is not required for instance, when the number of coaches or wagons in a train can be passed on to each block section after verification from the previous block section at the time the line clear indication is obtained (and with exchange of private numbers). The information is also provided to the section controllers. In some cases when working entirely within one block section, an 'LV' sign is not needed if the number of coaches or wagons is communicated by telephone to the next station.

LV board is also used by Sri Lanka Railways. This board is used for same purpose and is usually hung in a buffer of the last carriage. However, in DMUs, to indicate the last carriage (usually a driving/trailer car) red lights are used.

The Armagh rail disaster happened on 12 June 1889 near Armagh, County Armagh, in Ireland, when a crowded Sunday school excursion train had to negotiate a steep incline; the steam locomotive was unable to complete the climb and the train stalled. The train crew decided to divide the train and take forward the front portion, leaving the rear portion on the running line. The rear portion was inadequately braked and ran back down the gradient, colliding with a following train.

Railway signal Visual signal device for railway engineers

A railway signal is a visual display device that conveys instructions or provides warning of instructions regarding the driver’s authority to proceed. The driver interprets the signal's indication and acts accordingly. Typically, a signal might inform the driver of the speed at which the train may safely proceed or it may instruct the driver to stop.

Railway signalling The principle of signals used to control railway traffic

Railway signalling (BE), also spelled railway signaling (AE), is a system used to direct railway traffic and keep trains clear of each other at all times. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and momentum 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.

Brake van

Brake van and guard's van are terms used mainly in the UK, Ireland, Australia and India for a railway vehicle equipped with a hand brake which can be applied by the guard. The equivalent North American term is caboose, but a British brake van and a caboose are very different in appearance, because the former usually has only four wheels, while the latter usually has bogies. German railways employed Brakeman's cabins combined into other cars.

Emergency brake (train)

On trains, the expression emergency brake has several meanings:

Abergele rail disaster Train wreck

The Abergele rail disaster, which took place near Abergele, North Wales, in August 1868, was the worst railway disaster in Great Britain up till then.

The Train Protection & Warning System (TPWS) is a train protection system used throughout the UK passenger main-line railway network, and in Victoria, Australia.

British Rail Classes 101 and 102

The British Rail Classes 101 and 102 diesel mechanical multiple units were built by Metro-Cammell at Washwood Heath in Birmingham, England from 1956 to 1959, following construction of a series of prototype units. These classes proved to be some of the most successful and longest-lived of BR's First Generation DMUs, second in longevity only to the Class 121, with the final five units being withdrawn on 24 December 2003. The oldest set was, by then, just over 47 years old.

Railway brake Component of railway rolling stock

A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains.

Automatic Warning System

The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. Its operation was later extended to give warnings for;

The Charfield railway disaster was a fatal train crash which occurred on 13 October 1928 in the village of Charfield in the English county of Gloucestershire. The Leeds to Bristol London, Midland and Scottish Railway (LMS) night mail train failed to stop at the signals protecting the down refuge siding at Charfield railway station. The weather was misty, but there was not a sufficiently thick fog for the signalman at Charfield to employ fog signalmen. A freight train was in the process of being shunted from the down main line to the siding, and another train of empty goods wagons was passing through the station from the Bristol (up) direction.

Absolute block signalling

Absolute block signalling is a British signalling scheme 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. This system is used on double or multiple lines where use of each line is assigned a direction of travel.

UK railway signalling

The railway signalling system used across the majority of the United Kingdom rail network uses lineside signals to control the movement and speed of trains.

Australian railway signalling varies between the states of Australia, because each railway system was established under the different colonial governments with separate legislation. Just as with the notorious variation of Australian rail gauges, there are differing signal systems. The systems in New South Wales generally follow British precedents, although American influence has increased somewhat since the 1990s. Victoria uses American-style speed signalling on its main lines. That can cause confusion where the systems meet.

Penistone rail accidents List of rail accidents in Penistone South Yorkshire, England

Over the latter years of the 19th and early years of the 20th centuries, Penistone in Yorkshire gained a name as an accident black-spot on Britain's railway network; indeed, it could be said to hold the title of the worst accident black-spot in the country. The main line through the town was the Woodhead route of the Manchester, Sheffield and Lincolnshire Railway between Sheffield Victoria and Manchester, London Road. The line was heavily graded with a summit some 400 yards inside the eastern portal of the Woodhead tunnel.

This article contains a list of jargon used to varying degrees by railfans, trainspotters, and railway employees in the United Kingdom, including nicknames for various locomotives and multiple units. Although not exhaustive, many of the entries in this list appear from time to time in specialist, rail-related publications. There may be significant regional variation in usage.

The rolling stock used on the Isle of Man Railway today is entirely original but the serviceable passenger coaches number 14, out of an original total of 75 carriages. The 3 ft gauge railway was provided with a variety of stock from different manufacturers over its time, and types of coach were categorised according to a lettering system, with the original four-wheeled coaches being of A, B, C and D types, and so on. The F prefix encompassed all bogie vehicles including conversions from the A-D series. Letters G-M denoted goods stock. N referred to ex-Manx Northern Railway 6 wheel carriages. The types of stock can be summarised as follows:-

Railway semaphore signal Form of fixed railway signal

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.

Japanese railway signals

Japanese railway signals, according to the ministerial decree defining technical standards of railways, are defined as indicating operational conditions for railway staff driving trains.

The Kirtlebridge rail crash took place in 1872 at Kirtlebridge railway station in Dumfriesshire. An express passenger train ran into a goods train that was shunting; 11 people lost their lives immediately, and one further person succumbed later. The cause was a failure to communicate between the station master in charge of the shunting operation, and the signalman. There was not full interlocking of the points, and the block system of signalling was not in use.
