Device for energy supply of a train set consisting of at least one hybrid- or diesel-electric locomotive. The device comprises at least one gas driven electric power generator, driven by at least one engine or fuel cell which in turn are driven by gas from the at least one container or hydrogen storage facility, wherein the at least one electric power generator is connected to the locomotive electrical power supply networks. The device is arranged for supplying the train set with electrical current supply and/or idle current for a locomotive provided with or without automatic idle stop.

A primary circuit and a secondary circuit each have a switching element, each operate as a power conversion circuit while the switching element is activated, and each operate as a rectifier circuit while the switching element is deactivated. While a generator provided at the primary side of a first power conversion device is stopped, a controller activates the switching element of the secondary circuit and deactivates the switching element of the primary circuit. Accordingly, the first power conversion device converts electric power input from the secondary side and supplies electric power for causing the generator to operate. While the generator is operated, the controller activates the switching element of the primary circuit and deactivates the switching element of the secondary circuit such that the first power conversion device converts electric power supplied from the generator and outputs the converted electric power to the secondary side.

A system includes a drive system having one or more traction motors coupled in driving relationship to a plurality of wheels of a vehicle system. The traction motors are configured to provide both motive power for the vehicle system in a propel mode of operation and retarding effort to brake the vehicle system in a braking mode of operation. The system further includes a parking brake for maintaining a static position of the vehicle system when in an engaged state, and a controller configured to detect when the parking brake is in the engaged state. The controller is further configured to control at least one of the one or more traction motors to provide a braking effort to resist movement of the vehicle system when the parking brake is in the engaged state.

Various systems and methods are provided for identifying cylinder misfire. In one example, cylinder misfire may be identified based on a misfire monitor that differentiates a single-cylinder misfire event from a multi-cylinder misfire event based on output from a crankshaft speed sensor.

An energy recovery system for locomotives having a diesel engine to provide power for propulsion and also having non-propulsion electrical devices. The system includes a primary power battery to supply power to the non-propulsion electrical devices. The primary power battery is in electrical communication with a traction motor of the locomotive configured to send power to the primary power battery when the locomotive is coasting or braking.

An aircraft propulsion system (10) comprises at least first and second electrical generators (15a, 15b), each being configured to provide electrical power to a respective first and second AC electrical network (16a, 16b). The system (10) further comprises at least first and second AC electrical motors (19a, 19b) directly electrically coupled to a respective AC network (16a, 16b) and coupled to a respective propulsor (4), and a DC electrical network electrically coupled to the first and second AC networks (16a, 16b) via respective first and second AC to DC converters (17a, 17b), and to a further electrical motor 19c), the further electrical motor (19c) being coupled to a propulsor (4).

The cryogenic gas equipment unit designed for arrangement and operation of the gas treatment system for locomotives. The unit includes a sheet-lined housing with a power rack. An upper portion of the unit housing has a shape geometrically following the shape of the inner surface of the locomotive body roof. A flooring made of a cold-resistant heat-insulating material is attached to the bottom inside the unit. An aperture is made in one of the side walls of the unit housing. Temperature deformation compensators for cryogenic fuel lines and the cryogenic equipment unit housing are installed in the entry and exit points of the cryogenic fuel lines on the unit housing. A routine inspection of the equipment in the cryogenic gas equipment unit may be carried out through the aperture. In case a piece of the cryogenic gas equipment in the unit fails, the whole unit may be removed and replaced.
