A system for controlling a consist of rail vehicles or other vehicles includes a control unit electrically coupled to a first rail vehicle in the consist, the control unit having a processor and being configured to receive signals representing a presence and position of one or more tractive effort systems on-board the first vehicle and other rail vehicles in the consist, and a set of instructions stored in a non-transient medium accessible by the processor, the instructions configured to control the processor to create a optimization schedule that manages the use of the one or more tractive effort systems based on the presence and position of the tractive effort systems within the consist.

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.

Various methods and systems are provided for automatically applying tractive material during operation of a vehicle. In one embodiment, the application of tractive material for a vehicle is adjusted based on calculated and expected tractive effort for each powered truck, axle, or wheel of the vehicle. In this way, tractive material application is controlled on a per truck, axle, or wheel basis in order to reduce excessive use of tractive material during operation of the vehicle.

The invention relates to a screening element for screening and transporting grit material, for applying to a sanding device of a sanding apparatus for a vehicle. The screening element includes a plate element provided with a shaft-coupling mechanism, at least one through-opening, and at least one lug. The shaft-coupling mechanism is designed to couple the screening element to a shaft device of a rotary feeder of the sanding device. The through-opening is arranged in the plate element and is designed to guide grit material through the plate element. The lug extends transversely in relation to a main surface of the plate element, away from the plate element.

The invention pertains to a discharge nozzle for discharging grit or lubricant into the gap between a rail and a track wheel of a rail vehicle, with the discharge nozzle comprising a base body with at least one connection for being connected to a conveyor line for the grit or lubricant and an outlet that is connected to the connection via a channel. In order to achieve an efficient and purposeful discharge of the majority of grit and/or lubricant into the gap between the rail and the track wheel, the outer contour of the base body is in the longitudinal direction shaped in a convex manner at least in the rear region lying opposite of the outlet and, if applicable, surrounded by an attachment such that the air flowing around the base body is accelerated in the direction of the outlet.

A pneumatic sand conveying device for a sanding system of a rail vehicle includes an obstacle device which is fluidically coupled to a sand input for receiving sand from a sand storage container, the obstacle device being shaped to form an obstacle between the sand input and a mixing device fluidically coupled to the obstacle device. In addition, the sand conveying device has the mixing device for receiving and forwarding sand from the obstacle device by compressed air and a discharge device fluidically coupled to the mixing device to dispense the sand from the sand conveying device through a sand outlet. The obstacle device, the mixing device and the discharge device are arranged in a horizontal plane when the sand conveying device is in a state ready for operation.
