摘要: 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.

摘要: A control system receives signals representing a presence and position of a secondary movement system onboard a vehicle. The secondary movement system changes movement of the vehicle without generating thrust or propulsion to move the vehicle. The control system creates a schedule of use of the secondary movement system based on the presence and position of the secondary movement system and controls the secondary movement system based on the schedule that is created.
