What is ECP brake system?
From Wikipedia, the free encyclopedia. Electronically controlled pneumatic brakes are a type of modern railway braking system which offer improved performance compared to traditional railway air brakes.
What is ECP in railway?
Trains traditionally operate with a mechanical pneumatic braking system and some rolling stock has been fitted with an electronic overlay braking system commonly known as ECP braking.

How do electric train brakes work?
A conventional electric train braking system uses dynamic braking, where the kinetic energy of the train is dissipated as waste, mainly in the form of heat. When regenerative braking is employed, the current in the electric motors is reversed, slowing down the train.
Which braking system is used in Indian Railways?
Air Brake freight stocks on Indian Railway are fitted with single pipe/ twin pipe graduated release air brake system. Air brake system is most efficient and reliable braking system used to run heavy and long trains at high speeds. Recently, Bogie mounted Brake System (BMBS) has been introduced for freight stock.
Is pneumatic brakes are same as electrical brakes?
Pneumatic brakes are same as electrical brakes. Explanation: Pneumatic brakes are operated by fluid pressure. Internal shoe brakes are radial while external shoe brakes are axial brakes.
Who owns Westinghouse Air Brake?
WABCO Holdings was floated in a 2007 initial public offering by American Standard, WABCO’s owners for 30 years. On 28 March 2019, it was announced that WABCO Holdings was to be bought by ZF Friedrichshafen for $7 billion US dollars, with the transaction completed in 2020.
Do trains use regenerative braking?
The trains produce “regenerative braking energy” or “regenerative energy” during deceleration, which if properly captured and reused, can result in energy savings and peak demand reduction. Trains are powered by touching contact shoes against a direct-current (DC) “third rail” that runs parallel to the traction rails.
Does a train have emergency brakes?
Trains often have a facility in each car to enable passengers to apply the brakes in case of emergency. The driver can press an override button and hold the brakes off whilst they choose a safe place to stop the train.
Which brakes are used in railway train?
The vast majority of the world’s trains are equipped with braking systems which use compressed air as the force to push blocks on to wheels or pads on to discs. These systems are known as “air brakes” or “pneumatic brakes”.
Which brakes used in railway coaches?
3. Brake systems used in railway vehicles
- 3.1. Air and vacuum brakes.
- 3.2. Brake block.
- 3.3. Disc brakes.
- 3.4. Electrical controlled electro-pneumatic braking (ECP)
- 3.5. Electro-pneumatic braking (EP)
- 3.6. Dynamic braking.
- 3.7. Aerodynamic braking.
Are train brakes fail safe?
Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. A reduction or loss of air pressure signals each car to apply its brakes, using the compressed air in its reservoirs.
How does an ECP brake system work on a train?
In contrast, ECP braking uses electronic controls which make it possible to activate air-powered brakes on the cars. On an ECP-equipped train, the cars are equipped with a Trainline Cable that runs parallel to the brake pipe down the length of the train.
Where does the power come from on an ECP train?
On an ECP-equipped train, the cars are equipped with a Trainline Cable that runs parallel to the brake pipe down the length of the train. This cable is used to supply power to the electronic components installed on the cars.
How are pneumatic brakes used on a train?
Electronically controlled pneumatic brakes are a type of modern railway braking system which offer improved performance compared to traditional railway air brakes . Traditional train braking systems use pneumatic valves to control and generate brake applications on the cars along the length of the train.
What are the benefits of electronically controlled pneumatic brakes?
ECP provides many benefits over the traditional braking system. For example, since all the cars receive the brake command at the same time, the brakes are applied uniformly and instantaneously. This provides much better train control, shortens the stopping distances, and leads to a lower risk of derailment or of coupling breakage.
