What is the principle of brake system used in LHB coaches?
The LHB passenger coaches are equipped with a high-power air brake. It works together with all known high-power brake systems approved by UIC. The brake system of the coaches is compatible with locomotives. The brake control system is a friction brake system and is meant for pressure applied brake actuators.
How does a wheel slip protector work?
How does it work? WSP is a system fitted to most passenger trains to prevent the wheels from locking up due to low adhesion between wheel and rail. A signal is then sent to the relevant brake system on the affected bogie or axle, to release the brakes until the wheel returns to normal speed.
Which brake is used in railway coach?
Railway vehicles are commonly equipped with braking systems using compressed air to push the pads on the discs or blocks to the wheels. The systems are known as air or pneumatic brakes. The compressed air is conveyed through the train by a brake pipe.
What does WSP stand for engineering?
The Williams Sale Partnership Limited was established in 1969 as a building services consultancy in the UK. The company was floated on the London Stock Exchange in 1987 as WSP. Between 1990 and 1995, UK-based acquisitions added structural and civil engineering capability to WSP’s skills portfolio.
What is wheel shelling in LHB coaches?
Wheel shelling is a burning issue in LHB coaches. In this connection a check list (Annexure-A) has been prepared for LHB coaches found with minor wheel/skid/shelling. The data of such coaches should be monitored on regular basis to check whether such problems are occurring more than once in the same coach.
How many brake cylinders does an ICF coach have?
In order to overcome the problems of slack adjuster failure as well as problems associated with cast iron brake blocks, a design of brake system incorporating 8″ size two Page 10 No.IRCAMTECH/M/11-12/BMBS/1.0 Handbook on BMBS for ICF Coaches Page 3 of 47 cylinders on each bogie along with ‘K’ type high friction …
What is WSP system?
WSP system is the vital part of LHB & other FIAT fitted bogie coaches. WSP system is recently introduced in Indian Railways. Proper up keeping and maintenance of WSP system is necessary to ensure reliability and availability of coaches.
What is adhesion in locomotive?
• Adhesion is the ratio of drawbar force to locomotive weight. • The “dispatchable adhesion” is the overall adhesion rating. – a measure of how much a locomotive can pull.
Why do trains use air brakes?
The system went into use in 1872 on the Pennsylvania Railroad. Automatic air brakes soon gained widespread adoption around the world. They made braking safer and more precise and allowed railroads to operate at higher speeds, now that trains could be reliably stopped.
