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.

A method for operating a tractive vehicle and a vehicle combination are disclosed. A tractive vehicle includes a first friction brake device for generating a first stopping braking-force, a traction device for generating a tractive force and a control device for controlling at least the traction device. The method includes a step whereby the traction device is activated if a first undesired kinematic state is detected. Activation of the traction device would take place in such a way that a tractive force, counteracting the first undesired kinematic state, is generated and provided for deceleration to a standstill and/or for holding the tractive vehicle at a standstill.

Provided is a brake control system that can reduce use of a mechanical braking in a railway vehicle using an automatic train control (ATC). The present disclosure is a brake control system for a railway vehicle using an ATC. The brake control system includes: a main electric motor, a main conversion device, a brake controller, and an ATC device. The main electric motor generates a braking force by converting kinetic energy of a wheel of the railway vehicle to electrical energy. The main conversion device actuates the main electric motor. The brake controller outputs a braking signal to the main conversion device. The ATC device outputs a braking command to the brake controller based on the ATC. In addition, the ATC device outputs a preliminary braking signal for energizing the main electric motor prior to output of the braking command.

A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate. At least one bore is provided in the metering piston. To create a device which is of particularly simple and compact construction, a conveying air chamber separated from the pressure chamber and has a compressed air connection is provided, and at least one bore in the metering piston connects the conveying air chamber to the at least one outlet for the granulate, such that granulate can be conveyed to the at least one outlet by compressed air independently of the metering process.
