Wheel slide protection: Difference between revisions

Modern WSP systems are microprocessor controlled and employ two stage valves that permit fine control over the air pressure in the brake cylinders. This is essential to be able to capture and control a sliding wheel and to minimise the amount of air resource used by the WSP. WSP systems are now commonly being integrated into the brake controller equipment and frequently have to interface with electric brake systems (dynamic braking) to “blend” the brake effort provided by the friction and dynamic braking systems. Examples of this kind of equipment are manufactured by [[Knorr Bremse]] (EP compact, EP2002) and Faiveley Transport (EPAC). and POLI Wabtec (ATHENA).
