Abstract: A ballast discharge car having at least one non-pivoting transverse conveyor disposed beneath a hopper for distributing the ballast between the rails, near the outside of the rails, and well beyond the outside of the rails in a stockpiling application. The speed, direction, and angle of each conveyor is adjustable so that the ballast can be selectively cast a wide range of distances from the outside of the rails.

Abstract: An ultrahigh molecular weight polyethylene material is utilized in a railroad flangeway to reduce the wear of a railroad crossing base.

Abstract: A fluid impervious polymeric membrane separating a resilient pad from a railroad crosstie and having a width substantially greater than the resilient pad to resist moisture and mechanical forces in penetration between the concrete tie and the pad. The width is also sufficient to resist moisture penetration between the peripheral edges of the pad and the membrane. The width of the membrane is sufficient to extend essentially to the edge of the shoulder to limit lateral movement of the membrane caused by forces exerted by passing trains. Also, the membrane is substantially wider than the pad to extend essentially to the shoulder and insulator to resist lateral movement. Further, the pad is notched at a mid region adjacent to the insulator and clamp, with wider in regions, the notch resisting longitudinal movement of the membrane. The plastic material is selected from a group consisting of high density polyethylene, high molecular weight high density polyethylene and ultra high molecular weight polyethylene.

Abstract: An automatic rail securing device (10) mounted on a railroad car (12) upon which a device (20) for manipulating the track is mounted, as well as work positions to permit the placement of insulators (40) on the railroad ties (34) as well as clips (5). A clip securing apparatus (66) is slidably mounted to car 12 by means of wheels (15, 17) and struts (23, 25). The apparatus (66) includes two satellite stations (70, 72) which include a pair of compression members (74, 76) which automatically engage the clip (5) and secure it in a final position adjacent to the rail (32).

Abstract: An articulated vehicle in which one of the articulation pivots is mounted on the canopy of the vehicle. At least one of the hinge members of the pivot is in the form of a wide plate member to provide additional overhead protection for components mounted on the vehicle.
