Dead-man's Vigilance Device
A dead-man's vigilance device (also called the Driver Vigilance Device or DVD for short) is a railroad safety device that operates in the case of incapacitation of the driver. It is a hybrid between a dead-man's switch and a vigilance control. The main safety failing with the basic dead-man's control system is the possibility of the operating device being permanently held in position, either deliberately or accidentally. The dead-man's vigilance device was developed to detect this condition by requiring that the dead-man's device be released momentarily and re-applied at timed intervals. Modern practice Modern locomotive practice is to incorporate the dead-man's and vigilance functions under the control of the alerter or the event recorder. This enables more sophisticated monitoring of the driver's alertness. The vigilance control cycle time can then be speed dependent, varying inversely to train speed in order to reduce the distance the train may travel before a non-response ...

Railroad
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Driver
A train driver, engine driver, engineman or locomotive driver, commonly known as an engineer or railroad engineer in the United States and Canada, and also as a locomotive handler, locomotive operator, train operator, or motorman, is a person who drives a train, multiple unit or a locomotive. The driver is in charge of, and is responsible for the mechanical operation of the train, train speed, and all of the train handling (also known as brake handling). In American English, a hostler (also known as a switcher) moves engines around rail yards, but does not take them out on the normal tracks; the British English equivalent is a shunter. Train drivers must follow certain guidelines for driving a train safely. For instance, in general, train drivers are encouraged to favour longer stopping distances as this promotes vehicle health, safety, and passenger comfort. Career progression For many American railroads, the following career progression is typical: assistant conductor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead-man's Switch
A dead man's switch (see alternative names) is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness Loss may refer to: Arts, entertainment, and media Music * ''Loss'' (Bass Communion album) (2006) * ''Loss'' (Mull Historical Society album) (2001) *"Loss", a song by God Is an Astronaut from their self-titled album (2008) * Losses "(Lil Tjay son ..., or being bodily removed from control. Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software. These switches are usually used as a form of fail-safe where they stop a machine with no operator from a potentially dangerous action or incapacitate a device as a result of accident, malfunction, or misuse. They are common in such applications in locomotives, Aviation fuel, aircraft refuelling, elevator, freight elevators, lawn mowers, tractors, personal wate ...

Event Recorder
A train event recorder – also called On-Train Monitoring Recorder (OTMR), On-Train Data Recorder (OTDR), Event Recorder System (ERS), Event Recorder Unit (ERU), or simply Event Recorder (ER) – is a device that records data about the operation of train controls, the performance of the train in response to those controls, and the operation of other train control systems. It is similar to the flight data recorder found on aircraft. Functions Because event recorders are integrated with most car-borne systems, they are an attractive target for enhanced diagnostic and control functions. Some event recorders feature outputs controlling penalty braking or emergency braking systems, as well as speedometers. Data storage can be provided by magnetic tape, battery-backed RAM and, more recently, non-volatile EEPROM or flash memory, overwritten in a FIFO continuous loop. The data is intended for use in the investigation of accidents and other incidents, but is also used to moni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penalty Brake
A train protection system is a railway technical installation to ensure safe operation in the event of human error. Development Train stops The earliest systems were train stops, as still used by the New York City Subway, the Toronto subway, the London Underground, the Moscow Subway (only on the older lines) and the Berlin S-Bahn. Beside every signal is a moveable arm. If the signal is red, levers connected to valves on any passing train hit the arm, opening the brake line, applying the emergency brake, If the signal shows green, the arm is turned away from the levers and there is no contact. The Great Western Railway in the UK introduced its 'automatic train control' system in the early years of the 20th century. Each distant signal had before it a ramp between the running rails. If the signal showed green, the ramp was energised with a low voltage current which was passed to the locomotive when a shoe came into contact with the ramp. A bell rang in the locomotive's cab t ...

1987 Maryland Train Collision
The 1987 Maryland train collision occurred at 1:30 pm on January 4, 1987, on Amtrak's Northeast Corridor main line. The site of the crash was in the Chase community in eastern Baltimore County, Maryland, United States, at , about northeast of Baltimore. Amtrak train 94, the ''Colonial'', (now part of the ''Northeast Regional'') traveling north from Washington, D.C., to Boston, crashed into a set of Conrail locomotives running light (without freight cars), and which had fouled (entered) the mainline. Train 94's speed at the time of the collision was estimated at . Fourteen passengers on the Amtrak train were killed, as well as the Amtrak engineer and lounge car attendant. The Conrail locomotive crew failed to stop at the signals before , and it was determined that the accident would have been avoided had they done so. Additionally, they tested positive for cannabis. The engineer served four years in a Maryland prison for his role in the crash. In the aftermath, drug and alcohol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2008 Chatsworth Train Collision
The 2008 Chatsworth train collision occurred at 4:22:23 p.m. PDT (23:22:23 UTC) on September 12, 2008, when a Union Pacific freight train and a Metrolink commuter train collided head-on in the Chatsworth neighborhood of Los Angeles, California, United States. The scene of the accident was a curved section of single track on the Metrolink Ventura County Line just east of Stoney Point. According to the National Transportation Safety Board (NTSB), which investigated the cause of the collision, the Metrolink train ran through a red signal before entering a section of single track where the opposing freight train had been given the right of way by the train dispatcher. The NTSB blamed the Metrolink train's engineer, 46-year-old Robert M. Sanchez, for the collision, concluding that he was distracted by text messages he was sending while on duty. This mass casualty event brought a massive emergency response by both the city and county of Los Angeles, but the nature and e ...

Beresfield Rail Disaster
Beresfield railway station is located on the Main Northern line in New South Wales, Australia. It opened on 31 July 1925, serving the western Newcastle suburb of Beresfield. History Beresfield railway station opened on 31 July 1925. 1997 collision On 23 October 1997, Beresfield was the site of a major rail accident, when a FreightCorp coal train passed a red signal and collided with the rear of another coal train standing on the same track. Six people were injured, including the station master and a passenger who jumped from the platform moments before the collision. The crash resulted in dozens of coal wagons tumbling over the platform and across the tracks, blocking all four tracks and destroying most of the station. Three 82 class locomotives were destroyed. In 2002, Beresfield was fully redeveloped, receiving new easy-access facilities, station signage and booking office. Platforms & services Beresfield has one island platform with two faces. It is serviced by NSW TrainL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hinton Train Collision
The Hinton train collision was a rail transport accident that occurred in Canada on 8 February 1986. Twenty-three people were killed in a collision between a Canadian National Railway freight train and a Via Rail passenger train called the '' Super Continental'', including the engine crews of both trains. It was the deadliest rail disaster in Canada since the Dugald accident of 1947, which had thirty-one fatalities, and was not surpassed until the Lac-Mégantic rail disaster in 2013, which resulted in 47 deaths. After 56 days of testimony at a public inquiry, a commission concluded that the collision was caused by the freight head end crew failing to stop their train because of incapacitation or other unknown factors, while the conductor in the caboose failed to use the emergency brake to stop the train. The report also highlighted serious flaws in the culture and safety practices at Canadian National Railway. Background The collision occurred on a stretch of Canadian Nation ...
