A bogie for a high-speed railway vehicle includes a wheel set, an axle box, a primary spring suspension device, a frame, a secondary spring suspension device and a foundation braking device. A wheel of the wheel set has an LMA wheel tread. The foundation braking device is mounted by a three-point hitch structure. The axle box is a structure which is separatable in a vertical direction, and an off-line safety protecting device is mounted at a lower portion of the axle box. A traction rod of the secondary spring suspension device is a single traction rod. A center pin is provided with an integral hoisting device. Two anti-yaw dampers, as a group, are arranged at either side of the secondary spring suspension device, and the two anti-yaw dampers have the same damping coefficient.

A control system for use in an own motor vehicle is adapted and determined, based on surroundings data obtained by at least one surroundings sensor arranged at the own motor vehicle, to detect motor vehicles in the front and in the rear of the own motor vehicle and preferably to detect objects in front. The at least one surroundings sensor is adapted to provide, to an electronic control of the control system, the surroundings data representing an area in front of, next to and/or behind the own motor vehicle. The control system is at least adapted and determined to detect a first other motor vehicle participating in traffic in front of the own motor vehicle by means of the at least one surroundings sensor, to detect a second other motor vehicle participating in traffic in the rear of the own motor vehicle by means of the at least one surroundings sensor, to determine movements of the first and/or second other motor vehicles relatively (i) to a lane, on which the first and/or second motor vehicles or the own motor vehicle are, or (ii) relatively to the own motor vehicle, to determine a current driving situation of the own motor vehicle with respect to the current driving situation of the first and second other motor vehicles based on the movements of the first and/or second other motor vehicles and movements of the own motor vehicle, based on the current driving situation of the own motor vehicle with respect to the current driving situation of the first and second other motor vehicles, to repeatedly determine a measure of a brake requirement in the form of (i) a necessity measure, (ii) a time until the beginning of a deceleration and (iii) a deceleration measure for the own vehicle, and, provided that the necessity measure exceeds a predetermined threshold, trigger a deceleration of the own vehicle at a point in time which lies before the determined time until the beginning of a deceleration, wherein the triggered deceleration is less than the determined deceleration measure for the own vehicle.

A safety system for a train equipped with an ECP air brake arrangement, in which the train includes at least one locomotive and at least one railcar connected to a trainline network, the system including: at least one power supply; at least one power supply controller to communicate over the trainline network and control the at least one power supply; at least one local controller to: communicate over the trainline network; receive or determine railcar data including a condition or parameter associated with the at least one railcar; and, based at least partially on the railcar data, generate at least one first message to deactivate the at least one power supply. A computer-implemented method for monitoring and responding to at least one railcar's derailment is also disclosed.

Systems and methods for monitoring the integrity of a convoy of vehicles are described. The convoy can include a first vehicle and at least one second vehicle connected to the first vehicle. In one example, the system can include a communication line and a power supply line each arranged to be installed in the first vehicle and in the at least one second vehicle. The system can further include a control circuit arranged to verify whether the communication line is interrupted and verify whether the power supply line is interrupted. From the verifications, the control circuit may determine that both the communication line and the power supply line are interrupted and further determine that the second vehicle has disconnected from the first vehicle.

An emergency braking assembly for a motor-driven tool has a holding structure, a braking element movably mounted on the holding structure, and a wire-like actuation element, which has a shape-memory alloy. A first end of the actuation element is attached to the holding structure. A second end of the actuation element is drivingly coupled to the braking element. A method operates the emergency braking assembly. The braking element is set in motion by the actuation element and then a motion coupling between actuation element and braking element is cancelled or terminated.
