Abstract: An arrangement is proposed for controlled guidance of a wheel axle (22) or of a bogie of a rail vehicle passing over points, whereby the wheel contact point (48, 50) is subjected to a controlled influence such that the wheel axle runs substantially vertical to the track longitudinal axis. The controlled influence of the wheel contact point can be exerted by, for example, the stock rail (32) veering away outwards in the area that the blade begins.

Abstract: A continuous action track maintenance or rehabilitation machine comprises a first machine frame, a carrier frame arranged between the undercarriages supporting the first machine frame on the track, ballast tamping and track lifting and lining units vertically adjustably mounted on the carrier frame, and a drive linking the carrier frame to the first machine frame for longitudinally displacing the carrier frame with respect thereto. A second machine frame is linked to the rear end of the first machine frame, and a plow arrangement is vertically adjustably mounted on the second machine frame between the undercarriages thereof, the plow arrangement comprising a drive connecting the plow arrangement to the second machine frame for vertically adjusting the plow arrangement with respect thereto, a center plow for plowing ballast between the rails of the track, shoulder plows for plowing ballast laterally adjacent each one of the rails, and a drive for operating each one of the plows.

Abstract: A system and method for bracing and cushioning the impact of movable massive loads during sudden deceleration of a transport vehicle, such as created during humping of railway cars. Resilient elastomeric pads separate adjacent objects of the load with the thickness and density of the elastomeric material chosen to dampen typical impact forces without damage to the objects. The resilent pads are preferably formed with at least one face contoured to envelope the side of an object. Three types of resilient pads are disclosed for use in transporting massive sheet metal coils with one pad adapted for particular use at endwalls, another pad for use between coils, and yet another pad for use between mid-row coils and doorway dunnage.
Abstract: A railroad hopper car having bottom discharge doors, an elongated beam assembly along the bottom of the car, door operating levers to open and close the doors connected to the beam assembly and doors, and lost motion timing connections in the beam assembly which permits displacement of beam sections to open and close pairs or sets of doors in a sequential but substantially simultaneous and automatic order so ast to permit reduction of air pressure required to open the doors, or permit use of smaller diameter air cylinder, a pneumatic drive to move the beam in opposite directions to open and close the doors, and a secondary lock to maintain the beam stationary unless pneumatic pressure intentionally operates the pneumatic drive, with the lock being positioned to be readily seen when locked and safely operated if necessary from the wayside.
