There have been four railway accidents at Potters Bar (England). Those in 1898 and 1946 were signals passed at danger. The accident in 2002 led to substantial public debate and a national change in policy relating to maintenance of infrastructure.
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.
The Clapham Junction rail crash occurred on the morning of 12 December 1988, when a crowded British Rail passenger train crashed into the rear of another train that had stopped at a signal just south of Clapham Junction railway station in London, England, and subsequently sideswiped an empty train travelling in the opposite direction. A total of 35 people died in the collision, while 484 were injured.
On March 15, 1999, Amtrak's southbound City of New Orleans passenger train collided with a semi-trailer truck in the village of Bourbonnais, Illinois, United States. Most of the train derailed, killing eleven people. A National Transportation Safety Board (NTSB) investigation into the accident attributed the cause to the truck driver trying to beat the train across a grade crossing. The NTSB's recommendations from the accident included increased enforcement of grade crossing signals, the installation of train event recorders at all new or improved grade crossings, and procedures to provide emergency responders with accurate lists of all crew members and passengers aboard trains. The city of Bourbonnais erected a memorial near the site to commemorate those killed in the accident.
A wrong-side failure describes a failure condition in a piece of railway signalling equipment that results in an unsafe state. A typical example would be a signal showing a 'proceed' aspect when it should be showing a 'stop' or 'danger' aspect, resulting in a "false clear".
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 Ghotki rail crash occurred on 13 July 2005, at around 3:40am local time near Ghotki, Pakistan. No. 24 Dn train stopped at the station of Sarhad was hit from behind by the following Karachi Express train, causing several cars to derail; these were then hit by a third train running in the opposite direction (Tezgam). A total of seventeen train cars, carrying over 3000 passengers, were wrecked. Estimates of the death toll ranged as high as over 130. It was the worst train accident in Pakistan in fifteen years.
Classification of railway accidents, both in terms of cause and effect, is a valuable aid in studying rail 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.
There have been a number of train accidents on the railway network of Victoria, Australia. Some of these are listed below.
The Wenzhou train collision was a railway accident that occurred on 23 July 2011, when a high-speed train travelling on the Yong-Tai-Wen railway line collided into the rear of another stationary train on a viaduct in Lucheng District, Wenzhou, Zhejiang province, People's Republic of China. The two trains derailed, and four carriages fell off the viaduct. 40 people were killed, and at least 192 were injured, 12 of which were severe injuries. This disaster was caused by both defects in railway signal design and poor management by the railway company.
