Abstract: A self-propelled machine having a frame for receiving a truck which supplies ballast to a dispensing hopper at one end of the frame. A fluid system provides the locomotion and controls for the dispensing hopper. A turntable expedites conversion of the machine between road and rail use.

Abstract: A rail roller device constructed to include a cylindrically shaped roll surface, the ends of which are provided with radially extending end plates or flanges from which extend the roller shaft. Opposite ends of the roller shaft extend through steel ball bearings mounted within mounting brackets which are fixedly attached to the device frame. At least one retaining ring is located about the shaft between a ball bearing and an end plate. The generally rectangular shaped frame of the rail roller device is formed of four frame members each constructed from a length of angle iron. The frame is constructed so that a pair of frame members located parallel to the longitudinal axis of the roll surface can be set between rail ties.

Abstract: A method and apparatus of preplating ties including traversely aligning ties on a path, conveying along the path ties relative to a pair of plate guides, positioning a pair of plates on each tie adjacent the guides, attaching the plates to the tie by partially driving fasteners, continue aligning the plates relative to each other by conveying the tie relative to the guides and securing the plates to the tie during alignment by completing the driving of the fasteners. A tie guide is provided having a fixed guide parallel to the path and a biased pivotal guide extending at an angle to the fixed tie guide.
