Patent number: 11745707Abstract: A system and method for reducing the threat of derailment of a train during deceleration is provided. An individualized braking force for each rail car of a train, such individualized braking force being determined by the braking deceleration of the train's locomotive, may be calculated by the rail car's controller and is directly proportional to the mass of the rail car. The controller may utilize the various forces acting upon the individual rail car as measured by a plurality of sensing and measuring devices to dynamically adjust the braking force applied to the individual rail car's brakes. Such a system and method allows for the train to act as a single body mass when decelerating to eliminate rail car pile-up and reduce the threat of derailment.Type: GrantFiled: May 14, 2019Date of Patent: September 5, 2023Assignee: The United States Department of Transportation Federal Railroad AdministrationInventor: Phani Krishnaswamy Raj
