Classification of railway accidents , both in terms of cause and effect, is a valuable aid in studying rail (and other) accidents to help to prevent similar ones occurring in the future. Systematic investigation for over 150 years has led to the railways' excellent safety record (compared, for example, with road transport).
Ludwig von Stockert (1913) proposed a classification of accidents by their effects (consequences); e.g. -on-collisions, rear-end collisions, derailments. Schneider and Mase (1968) proposed an additional classification by causes; e.g. driver's errors, signalmen's errors, mechanical faults. Similar categorisations had been made by implication in previous books e.g. Rolt (1956), but Stockert's and Schneider/Mase's are more systematic and complete. With minor changes, they represent best knowledge.

The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia.
A train accident or train wreck is a type of disaster involving two or more trains. Train wrecks often occur as a result of miscommunication, as when a moving train meets another train on the same track, when the wheels of train come off the track or when a boiler explosion occurs. Train accidents have often been widely covered in popular media and in folklore.
In rail transport, a derailment is a type of train wreck that occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
A signal passed at danger (SPAD) is an event on a railway where a train passes a stop signal without authority. This is also known as running a red, in the United States as a stop signal overrun (SSO) and in Canada as passing a stop signal. SPAD is defined by Directive 2014/88/EU as any occasion when any part of a train proceeds beyond its authorised movement. Unauthorised movement means to pass:
The Southall rail crash occurred on 19 September 1997, on the Great Western Main Line at Southall, West London. An InterCity 125 high speed passenger train (HST) failed to slow down in response to warning signals and collided with a freight train crossing its path, causing seven deaths and 139 injuries.
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.
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 London, Midland and Scottish Railway (LMS) Leeds to Bristol 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.
The Harrow and Wealdstone rail crash was a three-train collision at Harrow and Wealdstone station in Wealdstone, Middlesex during the morning rush hour of 8 October 1952. The crash resulted in 112 deaths and 340 injuries, 88 of these being detained in hospital. It remains the worst peacetime rail crash in British history and the second deadliest overall after the Quintinshill rail disaster of 1915.
The Polmont rail accident, also known as the Polmont rail disaster, occurred on 30 July 1984 to the west of Polmont, near Falkirk, in Scotland. A westbound push-pull express train travelling from Edinburgh to Glasgow struck a cow which had gained access to the track through a damaged fence from a field near Polmont railway station, causing all six carriages and the locomotive of the train to derail. 13 people were killed and 61 others were injured, 17 of them seriously. The accident led to a debate about the safety of push-pull trains on British Rail.
On the evening of 4 December 1957, two trains crashed in dense fog on the South Eastern Main Line near Lewisham in south-east London, causing the deaths of 90 people and injuring 173. An electric train to Hayes had stopped at a signal under a rail bridge, and the following steam train to Ramsgate crashed into it, destroying a carriage and causing the bridge to collapse onto the steam train. The bridge had to be completely removed; it was over a week before the lines under the bridge were reopened, and another month before the bridge was rebuilt and traffic allowed over it.
There are a number of books on British railway accidents which provide aid in the systematic study of the causes and effects of accidents, and their prevention. There are common themes in many accidents. Key books are listed here to avoid repeating them for each individual accident.
The Darlington rail accident occurred on the evening of 27 June 1928 when a parcels train and an excursion train collided head on at Darlington Bank Top railway station in County Durham, England. The accident was caused by the parcels train driver passing a signal at danger, due to misunderstanding the signalling layout in an unfamiliar part of the station. This accident resulted in the deaths of 25 people and the serious injury of 45 people.
The Thirsk rail crash occurred on 31 July 1967 at Thirsk, Yorkshire, England on the British Rail East Coast Main Line.
Great Western Railway accidents include several notable incidents that influenced rail safety in the United Kingdom.
An accident occurred on the four-track mainline of the New York Central Railroad at 10:02 P.M. on March 27, 1953, 2.4 miles (3.9 km) east of Conneaut, Ohio. It began when an improperly secured load of pipe broke loose from a gondola car on an eastbound freight train, damaging the westbound passenger track. A passing westbound freight crew notified the first train and stopped to assess what had happened, but a fast westbound passenger train could not stop and was derailed by the damaged track, colliding with the adjacent westbound freight. Finally, an eastbound fast passenger train struck the derailed equipment from the first two trains. There were 21 deaths and 49 people were injured.
