Described herein are systems and methods providing a slip gear for an industrial cart. One embodiment includes a slip gear that includes a track gear for engaging with the track, a stabilizing bar, and a motor gear for engaging with a drive motor and the track gear. The slip gear may also include a stabilizing bar that is rotatably coupled to the track gear and the motor gear. In some embodiments, when the drive motor rotates the motor shaft, the motor gear rotates with the motor shaft to cause rotation of the track gear to propel the industrial cart. In response to an object pushing the industrial cart along the track, the stabilizing bar rotates to disengage the track gear from the track, thereby reducing friction between the industrial cart and the track.

A control device for a railway vehicle includes a housing and a cover covering an opening. The housing is provided with a pair of first members. The cover is provided with a second member having a plate shape. The contact of an edge of a hole portion of the second member with the vertically lower bottoms of edges of notch portions of the pair of first members causes the second member to be supported by the first members so as to be rotatable about a rotational axis. The contact of edges of the hole portion with the pair of first members restricts displacement of the second member.

An energy system for a vehicle system having a plurality of motors that may include a first power supply assembly that may also include a first battery assembly of a plurality of battery assemblies. The first power supply assembly also may include a first bus coupled to a first motor of the plurality of motors and coupled to the first battery assembly. A second power supply assembly may also be provided that includes a second battery assembly of the plurality of battery assemblies coupled to a second bus that is coupled to a second motor of the plurality of motors. A controller may also be provided that may be configured to vary conduction of electric current from the first battery assembly to the first motor by the first bus based on an operating condition of the second power supply assembly to provide a first input to the first motor that may be different than a second input provided to the second motor by the second battery assembly.

A rail vehicle for transporting passengers includes at least one car body, a passenger compartment situated in the car body, an underfloor region, an inner ceiling region, and a plurality of device containers for receiving vehicle components. The passenger compartment includes a first end wall region and a second end wall region which is situated opposite the first end wall region. In order to enable a great configuration freedom for the passenger compartment, it is provided that each device container of the rail vehicle is disposed in one of the above-mentioned regions.

A device for converting a diesel-electric locomotive into an electric locomotive includes operating components for an electric locomotive and an adapter frame on which the operating components are mounted. The adapter frame is designed so that it can be connected to connection points of a mechanical basic structure of the diesel-electric locomotive. There is also described a corresponding electric locomotive and a method for conversion.

Device for coupling a vehicle to a traction cable, comprising a fastening configured to couple the vehicle to the traction cable, the fastening including at least two rotatable elements configured to occupy a coupling position in which said at least two rotatable elements are in contact with the traction cable and the vehicle is coupled to the traction cable, the device including a variable speed drive configured to modify a speed of rotation of said at least two rotatable elements when said at least two rotatable elements are in the coupling position, so that the vehicle moves relative to the traction cable.

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.
