Abstract: A spraying apparatus for applying a friction modifying fluid to a railroad rail, comprising: a nozzle body disposed in a housing; a fluid inlet conduit in fluid communication with an opening in housing; a fluid inlet disposed in the housing in fluid communication with a first fluid conduit defined by or disposed in the nozzle body; wherein the first fluid conduit runs from fluid inlet to a hollow nozzle tip body disposed on and protruding through a bottom of housing and wherein fluid inlet is also disposed below, and in fluid communication with, the fluid inlet conduit; a control fluid supply line and an atomizing fluid supply line each partially disposed in the housing and each having respective portions external of the housing for connecting with the same fluid supply or respective fluid supplies; wherein the control fluid supply line injects a pressurized control fluid against a piston assembly disposed in a piston cavity; wherein the piston assembly carries stopper needle which is biased towards hollow nozzle tip body by a spring so that the needle closes a nozzle tip opening of hollow nozzle tip body; wherein the atomizing fluid supply line provides a pressurized atomizing fluid into hollow nozzle tip body to atomize the first fluid supplied by the first fluid conduit into the hollow nozzle tip body via a fluid cap disposed on the hollow nozzle tip body; wherein in operation the control fluid supply line and the atomizing fluid supply line are operated simultaneously while the first fluid is supplied by the first fluid conduit into the hollow nozzle tip body via a fluid cap such that the pressurized control fluid injected by control fluid supply line against a piston assembly displaces needle out of the nozzle tip opening and allows the first fluid to exit out of the nozzle tip opening where the first fluid is atomized by the pressurized atomizing fluid supplied by the atomizing fluid supply line.

Abstract: 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.

Abstract: Disclosed is a control system and method for controlling a superturbocharged engine system in various operation modes. Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For transient control mode, the control system may respond to transient conditions in response to engine speed and load so that the engine does not bog down or overcome vehicle traction limits. The control system may also predict future operating points.

Abstract: Provided is a controlling device for a railway electric car, the controlling device being able to detect a slipping/sliding phenomenon during, in particular, high-speed travel and to exercise slipping/sliding control in an appropriate manner. A slip controlling unit 1 includes a first adhesion level index generating unit and a second adhesion level index generating unit. In a normal slipping state in which an acceleration changes instantaneously, torque control is exercised by using a first adhesion level index generated by the first adhesion level index generating unit based on an acceleration deviation and a speed deviation. In a slipping state during high-speed travel, because the acceleration deviation and the speed deviation are small, torque control is exercised by using a second adhesion level index generated by multiplying the first adhesion level index by a gain equal to or smaller than 1 generated by the second adhesion level index generating unit.

Abstract: At least one powered disc is suspended from a locomotive and applied to a rail surface for treating the rail surface ahead of driven locomotive wheels to increase adhesion between the driven wheels and the rail surface. Torque applied to the disc varies the rate of rotation of the disc away from that of a freely-rotating disc so that a significant level of creep may be maintained between the disc and the rail surface with substantially no angle of attack between the disc and the longitudinal axis of the rail. The torque may be generated through a second disc contacting the rail and coupled to the first disc with the first and second discs rotating with differing rates of rotation, or may be generated through a passive or active actuator coupled directly to the disc. The amount of creep between the disc and the rail surface and the direction of the creep may be varied in accordance with the level of contamination of the rail and the disc may be disengaged from the rail when cleaning is not required.
