Emergency Brake (train)
On trains, the expression emergency brake has several meanings: * The ''maximum'' brake force available to the engine driver from the conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab. * A completely separate mechanism from the conventional braking system, designed to stop the train as quickly as possible. * A handle or plunger which may be applied by a passenger in an emergency, either stopping the train directly or sending an alarm to the driver so that they can stop the train. Industry vernacular for when the emergency brake is applied is go into emergency, as in phrases like "the train may fail to go into emergency" or "the ability of the train to go into emergency is paramount". The emergency brake applies considerably more braking force than the standard full-service brake. The engine driver or motorman will only use the emergency brake as a last resort, s ...

S-Bahn
The S-Bahn ( , ), , is a hybrid urban rail, urban–suburban rail system serving a metropolitan region predominantly in German language, German-speaking countries. Some of the larger S-Bahn systems provide service similar to rapid transit systems, while smaller ones often resemble Commuter rail, commuter or even regional rail systems. The name ''S-Bahn'' derives from (), (, not to be confused with the present-day ''Stadtbahn'') or (). Similar systems in Austria and German-speaking Switzerland are known as S-Bahn as well. In Belgium, it is known as S-Trein (Flemish dialects, Flemish) or Train S (French language, French). In Denmark, they are known as S-tog , and in the Czech Republic as Esko or S-lines. In Milan, they are known as Milan S Lines, Linee S. S-Bahn is also a treated as a Train categories in Europe, train category in several European countries.

Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, Railroad car#Freight cars, freight and Passenger railroad car, passenger cars (or coaches), and Railroad car#Non-revenue cars, non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, Railcar, single or Multiple unit, multiple units. In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock comprising a train, a list containing specific information for each car of a train, or a group of locomotives. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then ship ...

Butterfly Valve
A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. Principle of operation Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regulation Of Railways Act 1889
The Regulation of Railways Act 1889 ( 52 & 53 Vict. c. 57) is an Act of the Parliament of the United Kingdom. It is one of the Railway Regulation Acts 1840 to 1893. It was enacted following the Armagh rail disaster. Safety It empowered the Board of Trade to require any railway company to: * adopt the block system of signalling on any passenger railway; * provide for the interlocking of points and signals on such railways; * provide for and use on all passenger trains continuous brakes; the brakes must be instantaneous in action; self applying in the event of any failure in continuity; capable of being applied to every vehicle of the train; and in regular use in daily working. Provision was made to enable the railway companies to issue debentures to pay for the capital cost of the equipment. There were also provisions regarding reporting the number of persons in safety-related employment who worked more than a specified number of hours. Tickets The Act also requires passen ...

Track Brake
A magnetic track brake (Mg brake) is a brake for rail vehicles. It consists of brake magnets, pole shoes, a suspension, a power transmission and, in the case of mainline railroads, a track rod. When current flows through the magnet coil, the magnet is attracted to the rail, which presses the pole shoes against the rail, thereby decelerating the vehicle. While brakes such as disc brakes or shoe brakes depend on the frictional connection between wheel and rail, the magnetic track brake acts directly on the rail. Therefore, its brake effect is not limited by wheel-rail contact. Thus, environmental factors such as wetness or contamination of the rail have less influence on the brake force. Usage Magnetic track brakes are used on rail vehicles in addition to the primary, wheel-effective brake systems. As an additional brake system, they help to ensure that the prescribed brake distances of rail vehicles can be complied with. Since magnetic track brakes always act unregulated an ...

Emergency Brake On Bombardier Commuter Railcars
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, he ...

Indian Rupee
The Indian rupee (symbol: ₹; code: INR) is the official currency of India. The rupee is subdivided into 100 '' paise'' (Hindi plural; singular: ''paisa''). The issuance of the currency is controlled by the Reserve Bank of India. The Reserve Bank derives this role from powers vested to it by the Reserve Bank of India Act, 1934. Etymology Pāṇini (6th to 4th century BCE), the ancient Indian grammarian and logician, writes of the (). While it is unclear whether Panini was referring specifically to coinage, some scholars conclude that he uses the term ''rūpa'' to mean a piece of precious metal (typically silver) used as a coin, and a ''rūpya'' to mean a stamped piece of metal, a coin in the modern sense. The ''Arthashastra'', written by Chanakya, prime minister to the first Maurya emperor Chandragupta Maurya (), mentions silver coins as . Other types of coins, including gold coins (), copper coins (), and lead coins (), are also mentioned. The immediate precursor to t ...
