An adjustment device for a track conditioning unit has a measuring unit for determining a lateral offset of a rail, travelled on by a rail vehicle, relative to an effective range of a track conditioning unit or a measuring unit for determining the relative position of a bogie with respect to the rail car body. The adjustment device contains a determining unit for determining an actuation command for an actuation unit in accordance with the determined lateral offset between the effective range of the track conditioning unit and the rail. Part of the adjustment device for the track conditioning unit is also an actuation unit for actuating an actuator unit of the track-conditioning unit with an adjustment command which is generated on the basis of the actuation command. The actuator unit adjusts an effective range of the track conditioning unit on the basis of the adjustment command.

Examples for a traction system are provided. In one example, the traction system includes a nozzle coupled to an air source and configured to be selectively aimed toward a determined portion of a rail surface of a rail, and a conduit configured to supply pressurized air from the air source to the nozzle, the nozzle flexibly coupled thereto. The nozzle is configured for the aim of the nozzle to be controlled to change its aiming direction in response to a change in curvature of the rail, whereby a stream of air from the nozzle impacts the determined portion during movement of the vehicle through the curvature of the rail.

A discharge device for granular materials, with a housing having at least one inlet for the granular materials, and with a rotor that is connected to a motor, rotates about an axis of rotation and has multiple vanes and chambers located between the vanes, the granular materials being conveyable from the at least one inlet to at least one outlet when the rotor rotates. The axis of rotation of the rotor is vertical and the rotor is preferably arranged inside an essentially cylindrical wear liner.

The present invention relates to a sand dispenser for a rail vehicle, wherein the sand dispenser comprises a metering device, a delivery device and an uncoupling device. The metering device is designed to pneumatically meter a desired quantity of sand using a metering air flow. The delivery device is designed to pneumatically deliver the quantity of sand to at least one scattering site using a delivery air flow. The uncoupling device is designed to pneumatically uncouple the metering device and the delivery device, wherein the uncoupling device is designed to provide a compensating air flow for compensating a difference between an output air flow of the metering device and an input air flow of the delivery device.

A sandbox for rail vehicles, of a type comprising a sand container, on the bottom of which there is a hollow body which presents one or several openings through which sand flows out towards an ejector assembly beneath by passing through an outlet hole controlled by an axially sliding vertical shutter located inside the hollow body is provided. The shutter translates between a lower position in which the output hole is closed and an upper, maximum opening position, whereby the shutter features a cylindrical shape and its lower end functionally cooperates with a ring shaped, sealing coaxial seat, corresponding to the outlet hole of the container.

A rail conditioning system associated with a locomotive is provided. The locomotive operates on a rail. The rail conditioning system includes a fluid supply tank. The rail conditioning system also includes a first nozzle coupled to the locomotive. The first nozzle is adapted to direct a first beam of fluid received from the fluid supply tank towards a first portion of the rail. The rail conditioning system further includes a second nozzle coupled to the locomotive. The second nozzle is adapted to direct a second beam of fluid received from the fluid supply tank towards a second portion of the rail. The rail conditioning system includes a valve element provided in fluid communication with the first and second nozzles. The rail conditioning system further includes a control module in communication with the valve element.
