In 1968 American Standard purchased Wabco. [8] WABCO's direct successor companies include WABCO Vehicle Control Systems, a commercial vehicle air brake manufacturer now owned by ZF Friedrichshafen; and Wabtec, a railway equipment manufacturer, which have been owned and operated independently of each other since the mid-twentieth century.
Piping diagram from 1909 of a Westinghouse 6-ET Air Brake system on a locomotive Control handle and valve for a Westinghouse air brake. A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1]
WABCO Holdings, Inc. was a U.S.-based provider of electronic braking, stability, suspension and transmission automation systems for heavy-duty commercial vehicles. [2] In 2007, the Vehicle Control Systems was spun off as WABCO Holdings Inc., an American provider of electronic braking, stability, suspension and transmission automation systems for heavy-duty commercial vehicles.
1990s: First trials on BN. TSM of Kansas City operated more than eight coal and intermodal trains using their "EABS" ECP for BN, CP, and Amtrak. TSM was purchased by Wabco in 1998. October 11, 2007: The first ECP-equipped Norfolk Southern train in the United States began operating. [9] [10]
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the ...
Wabtec facility, Greensburg, Pennsylvania. Westinghouse Air Brake Technologies Corporation, commonly known as Wabtec, is an American company formed by the merger of the Westinghouse Air Brake Company (WABCO) and MotivePower Industries Corporation in 1999.
In intermediate level ESC systems, ABS will be disabled, or the computer will actively lock the wheels when brakes are applied. In these systems, or in vehicles without ABS, the performance in emergency braking in slippery conditions is greatly improved as grip state can change extremely rapidly and unpredictably off-road when coupled with inertia.
During heavy braking, preventing wheel lock-up helps the driver maintain steering control. Four channel ABS systems have an individual brake line for each of the four wheels, enabling different braking pressure on different road surfaces. Three channel systems are equipped with a sensor for each wheel, but control the rear brakes as a single ...
