A method of cleaning a railhead uses a high pressure water abrasive slurry system. A slurry including an abrasive particulate and water is applied to the railhead at a pressure of at least 350 bar. A train incorporates an apparatus for cleaning a railhead, which includes a slurry mixing unit configured to contain a slurry including an abrasive particulate and water. At least one nozzle is in fluid communication with the slurry mixing unit. The at least one nozzle is configured to apply the slurry to the railhead at a pressure of at least 350 bar.

A system and method herein relate to vehicle control by adjusting a torque distribution of the vehicle. The system includes a first motor configured to provide a torque to a first wheel, and a delivery system configured to controllably apply a traction control compound to a route on which the first wheel is configured to travel. The system also includes a controller circuit having one or more processors. The controller circuit is configured to control the delivery system to apply the traction control compound to the route based on a monitored temperature of the first motor.

Methods and systems for a mounting device for mounting debris deflector to transportation vehicles such as light rail which helps to position the deflector at the front or rear end of vehicles are disclosed. The mounting device is located between the deflector and transportation vehicle and includes a longitudinal member having a proximal end and a distal end, a first base plate rigidly connected to the proximal end of the longitudinal member, and a second base plate rigidly connected to the distal end of the longitudinal member. Further, the first base plate may be connected to understructure of the transportation vehicle, and the second base plate may be connected to the debris deflector.

A system and method are provided for subvehicularly accessed treatment of ground surfaces about a rail track occupied by a rail vehicle. A mobile treatment unit having a propulsion mechanism for subvehicular passage between the rails occupied by the rail vehicle includes a dispensing portion for expelling a treatment material therefrom onto regions of the ground surface about the rails. The mobile treatment unit is maneuverable between the rails and maintains height clearance for unobstructed passage beneath the occupying rail vehicle. At least one sensor unit is coupled to the mobile treatment unit, which acquires environmental feedback data about the mobile treatment unit. A control unit is operably linked to the mobile treatment and sensor units, and receives the environmental feedback data. The control unit controls actuation of the mobile treatment unit responsive to the environmental feedback and/or a maneuver control command.

An apparatus for buffing rails includes a wheel frame having a front end and a back end, and a buffer frame. The buffer frame is pivotably attached to the wheel frame to modulate contact between the buffer heads and the rails. The wheel frame includes two front guide wheels, located on opposing sides of the front end of the frame, and a rear guide wheel located at the back end of the frame. The front guide wheels and the rear guide wheel are configured to engage the rails. The buffer frame includes two circular buffer heads, located at opposing sides of the buffer frame between the front and rear guide wheels. The buffer heads are configured to contact the rails. The buffer frame further includes an engine located at the buffer frame. The engine is configured to drive the rotation of the buffer heads to buffer the rails.
