A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective ...
A railway air brake is a railway brake power braking system with compressed air as the ... 620 kPa) for freight trains and 110 psi (7.6 bar; 760 kPa) for passenger ...
As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders. To release the brakes, the engineer charges the brake pipe. This method of controlling the brakes on freight and passenger cars has remained virtually unchanged since its invention by George Westinghouse in 1868.
An ETD on a container train in 2005. 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 replacement of a caboose.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
However, the Regulation of Railways Act 1889 was only specific to passenger trains, and any carriages and wagons that may form a passenger train. [3] Freight trains, were still not required to have a continuous brake system, thus brake vans still remained a fixture on freight trains, and runaways still occurred.
The Kunze-Knorr brake brought together the ideas of Prussian senior surveyor, Bruno Kunze (1854–1935), and preparatory work by the founder of Knorr-Bremse, Georg Knorr (1859–1911). It was the first, continuous, compressed-air brake that, even on long goods trains, enabled the brake force not only to be applied gradually, but also released ...
