This disclosure discloses a braking-recovery system and method for a train, and a train. The system includes: a traction network, a train, and an energy storage power station. The energy storage power station is connected to the traction network, the energy storage power station includes a second controller, and the second controller controls the energy storage power station according to the voltage of the traction network to perform charging or discharging. The train includes: an electric brake; a battery; a distributor, connected to the electric brake, where there is a node between the distributor and the electric brake; a bidirectional DC/DC converter, where one end of the bidirectional DC/DC converter is connected to the battery, and another end of the bidirectional DC/DC converter is connected to the node; and a first controller, used to control, when the train is braked, the distributor and the bidirectional DC/DC converter to feed back braking electric energy of the train to the traction network, and control the bidirectional DC/DC converter according to a voltage of the traction network to absorb the braking electric energy of the train by using the battery.

A locomotive consist including a pair of fuel-electric locomotives, each having a prime mover engine and a power transmission system including a main generator and traction motors coupled to driving wheels, a high voltage electrical connection operable in an on state or an off state, and a computer controller. The pair of fuel-electric locomotives is configured to selectively cooperate to operate in three different operating modes as controlled by the computer controller: (1) a prime mover mode, (2) a mother/slug mode, and a mother/inoperative mode.

A high-power plug connection system has a cable connection housing for connecting at least two electric high-power plug connectors in order to transmit and/or distribute a high current strength and/or a high electric voltage. The cable connection housing receives at least two insulating bodies for receiving at least one respective high-power contact and at least one electrically conductive rail in an interior. The rail is designed to establish an electrically conductive connection between the at least two high-power contacts, and the insulating bodies protrude at least partly out of the interior through a respective housing opening and into a connection region, the connection region being designed to receive the high-power plug connector.

A detector detects physical quantities relating to an operation of a vehicle air-conditioning device at a predetermined sampling frequency to generate groups of time-series data items. A volatile tracking memory has a work area to which the groups of time-series data items for a tracking period is writable. A record holding power accumulator supplies, to the tracking memory, power used for holding in the work area the groups of time-series data items. A writer sequentially overwrites the groups of time-series data to the work area of the tracking memory and stops overwriting of the groups of time-series data items to the work area when an abnormality occurs in the vehicle air-conditioning device.

A plurality of apparatuses mounted on cars are monitored and controlled by control devices mounted on the cars. A display device capable of displaying apparatus information of the apparatuses is mounted on a driver's cab. A display screen of the display device is configured by arranging a plurality of display components by which apparatus information of each of the apparatuses can be displayed. A software generating device determines arrangement positions of the display components arranged on the display screen, automatically generates layout design data of the display screen, and automatically generates software for generating the display screen on the basis of the layout design data. The arrangement positions of the display components respectively representing the apparatuses when a number of apparatuses of the same type are monitored and controlled by one and the same control device are determined according to arrangement rule information that is exceptional rules.
