A DC-feeding-voltage calculating apparatus includes storage that stores train model information including information for controlling a regenerative power reducing amount in a train in an electrified section; feeding network model information including position information on a substation; and substation model information including control information on a substation voltage. On the basis of: the stored information; a voltage value, current values of feeders by train direction, the voltage and current values being measured in the substation; and first train information on a train including a wireless communication apparatus, an estimator estimates second train information on a train not including a wireless communication apparatus and outputs train operation information. A calculator, on the basis of the stored information and the train operation information, calculates a substation voltage setting value for controlling the substation voltage such that regenerative power is increased in a regenerative car in the electrified section.

An apparatus for restricting a contact head of a catenary grounding device unintentionally falling from a catenary in use that is connectable to the contact head. The apparatus forming part of a contact head of a catenary grounding device for restricting the contact head unintentionally falling from a catenary in use.

A total task vehicle (TTV) may operate indoors to move a variety of different types of materials and accomplish a variety of different types of tasks, using tools and accessories powered by/connected to the TTV. One or more high power density (HD) battery packs may provide both 240V DC to 380V DC and 120V AC power to propel the TTV and also to function as a generator for tools and accessories attached to the TTV. A high torque/high speed convertible drive system may allow the TTV to operate in a ride-on mode, a walk-behind mode, providing for flexibility and adaptability in use of the TTV.

An alignment assist assembly for a work machine includes a camera supported to a lateral side of the work machine and at an elevation above at least one power rail, the camera being oriented toward the haul route and configured to capture an image field and generate an image signal indicative of the image field. A display is operably connected to the camera and disposed in the cab, the display configured to generate a displayed image based on the image signal from the camera. The display further is configured to display an alignment overlay indicative of a range of distances between the frame and the at least one power rail that permit the current collector to engage the surface of the at least one power rail.
