A device supplies energy to a sensor arrangement in a rail vehicle. The device has a housing in which there is arranged a coil which can be inductively coupled to a motor cable carrying an alternating current. The housing is embodied to enclose part of a length of the motor cable, and the coil is wound around an annular coil core which concentrically or substantially concentrically surrounds the motor cable. The housing has multiple parts including at least one first and one second housing part. The annular coil core is implemented in multiple parts and a first coil core part is arranged in the first housing part and a second coil core part is arranged in the second housing part. The housing is further embodied to mechanically secure the motor cable to a component of the rail vehicle and/or to mechanically connect the motor cable to a further motor cable.

A system and a method for monitoring pressure inside a railway vehicle comprise a carriage pressure detection device, a control device, and an alarm device. The control device is configured to receive and process a pressure signal collected by the carriage pressure detection device, perform calculation on and analyze the collected data, and transmit an alarm signal to the alarm device as an alarm when a preset alarm condition is met. When a pressure protection device fails, pressure changes inside the vehicle are monitored in real time by the carriage pressure detection device functioning independently of the pressure protection device.

A drive system for a rail vehicle includes at least one drive motor and at least one cooling apparatus for cooling the at least one drive motor and/or other components of the drive system, in particular a current converter. The drive system is constructed and intended to use kinetic energy of the rail vehicle for operation of the cooling apparatus. A rail vehicle having the drive system and methods for the forward movement of a rail vehicle are also provided.

A train, comprising a train formation consisting of a head car, a power car and an intermediate car, end walls of the head car, power car and intermediate car having thereon oppositely disposed connectors 2 extending perpendicular to a direction of travel of the train; all connectors 2 on the end walls of the train are connected by means of wiring; the head car, power car and intermediate car connect electric power wiring of the whole train by means of the connectors when in any formation state; the train has disposed thereon two parallel power supply wires penetrating the entire train and multiple auxiliary power supply systems. The present invention can decrease different voltage standard conversion equipment of a multiple unit, lowering in-vehicle equipment costs.

A rail vehicle is provided, including: a floor, where an opening portion is formed in the floor, and the opening portion includes a wheel inspection opening and a wheel mounting opening; a wheel, disposed at the wheel mounting opening, where a part of the wheel passes through the wheel mounting opening and protrudes from an upper surface of the floor, and a wheel cover covers an upper side of the wheel; and an inspection floor panel, detachably connected to the wheel inspection opening, where the wheel inspection opening is located on one side of the wheel in a left-right direction of the rail vehicle.
