An air brake or, more formally, a compressed air brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle.
An air compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air).
České dráhy, often shortened to ČD (English: Czech Railways), is the main railway operator in the Czech Republic providing regional and long-distance services.
A bogie (in some senses called a truck in North American English) is a chassis or framework carrying wheelsets, attached to a vehicle, thus serving as a modular subassembly of wheels and axles.
A brake shoe is the part of a braking system which carries the brake lining in the drum brakes used on automobiles, or the brake block in train brakes and bicycle brakes.
British Railways (BR), which from 1965 traded as British Rail, was the state-owned company that operated most of the rail transport in Great Britain between 1948 and 1997.
A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Compressed air is air kept under a pressure that is greater than atmospheric pressure.
In rail transport, distributed power (DP) is a generic term referring to the physical distribution—at intermediate points throughout the length of a train—of separate motive power groups.
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive.
The Electro-pneumatic brake system on British railway trains was introduced in 1950 and remains the primary braking system for multiple units in service today.
Electronically controlled pneumatic brakes are a type of modern railway braking system which offer improved performance compared to traditional railway air brakes.
On trains, the expression emergency brake has several meanings.
The end of train device (ETD), sometimes referred to as an EOT, flashing rear-end device (FRED) or sense and braking unit (SBU) is an electronic device mounted on the end of freight trains in lieu of a caboose.
A fail-safe in engineering is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause no or minimal harm to other equipment, the environment or to people.
The Federal Express (later officially known as just the Federal) was an overnight named passenger train run by the Pennsylvania Railroad and the New York, New Haven and Hartford Railroad between Washington, DC's Union Station and Boston, Massachusetts's South Station from 1912 to 1971.
The Gare de Lyon rail accident occurred on 27 June 1988, when an SNCF commuter train headed inbound to Paris's Gare de Lyon terminal crashed into a stationary outbound train, killing 56 and injuring 55.
Theodor Georg Knorr (October 19, 1859 in Ruda bei Neumark, West Prussia – April 15, 1911 in Davos, Switzerland), was an engineer and entrepreneur on the field of railroad technology and founder of the company Knorr-Bremse.
George Westinghouse Jr. (October 6, 1846 – March 12, 1914) was an American entrepreneur and engineer based in Pittsburgh, Pennsylvania who invented the railway air brake and was a pioneer of the electrical industry, gaining his first patent at the age of 19.
A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, or from a locomotive to railway air brakes on railroad cars.
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal.
The Intercity-Express (written as InterCityExpress in Austria, Denmark, Switzerland and, formerly, in Germany) or ICE is a system of high-speed trains predominantly running in Germany and its surrounding countries.
Knorr-Bremse ("Bremse" meaning brake) is a manufacturer of braking systems for rail and commercial vehicles that has operated in the field for over 110 years.
The Kunze-Knorr brake (Kunze-Knorr-Bremse or KK-Bremse) is an automatic compressed-air brake for goods, passenger and express trains.
The London, Brighton and South Coast Railway (LB&SCR; known also as "the Brighton line", "the Brighton Railway" or the Brighton) was a railway company in the United Kingdom from 1846 to 1922.
The length of a train, including the longest trains, may be measured in number of wagons (for bulk loads such as coal and iron ore) or in metres for general freight.
Maschinenfabrik Oerlikon was a Swiss engineering company based in the Zürich district of Oerlikon known for the early development of electric locomotives.
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere; it is also considered by some to be a northern subcontinent of the Americas.
The Pennsylvania Railroad (or Pennsylvania Railroad Company and also known as the "Pennsy") was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania.
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms.
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapour flow into an engine.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Brakes are used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them standing when parked.
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa.
Telemetry is an automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring.
Thermodynamic equilibrium is an axiomatic concept of thermodynamics.
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s.
Washington Union Station is a major train station, transportation hub, and leisure destination in Washington, D.C. Opened in 1907, it is Amtrak's headquarters and the railroad's second-busiest station with annual ridership of just under 5 million.
The Westinghouse Air Brake Company (sometimes nicknamed or abbreviated WABCO although this was also confusingly used for spinoffs) was founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania.
