Abstract: A steel tie for incorporation in rail track has a horizontal rectangular plate for connection transversely of the rail to restrain vertical rail movement. The longer sides of the horizontal plate terminate in downwardly and outwardly inclined margin portions for capturing ballast. A web member extends vertically on the underside of the plate member and parallel to and centrally of the longer sides of the plate and serves to restrain longitudinal rail movement. Curved ballast engaging plate members are connected on the underside of the tie to provide lateral stability. The plate members are detachable and replaceable with smaller or larger members to provide a smaller or greater ballast engaging area. The lower edge of the vertical web has a thickened portion to carry stresses. Rail fastening devices consist of a pair of opposing longitudinally extending shoulders adapted to accommodate the rail flange between them. Each shoulder has a downwardly facing abutment surface, and a resilient rail clip has an intermediate portion that bears upwardly on the abutment surface, an end portion that extends inwardly from the abutment surface and bears resiliently on the upper side of the rail flange.

Abstract: A machine for collecting tie plates strewn along a rail bed includes a frame adapted for travel along a railroad in a forward direction. A pickup drum having magnetic properties is rotatably supported by the frame and extends over a bed portion of the railroad. A top drum is mounted at a location that is higher and forward of the pickup drum and rotates parallel to the pickup drum. An endless conveyor circulates around the pickup and top drums, and a separation drum is disposed between the pickup drum and the top drum along an ascending portion of the endless conveyor. The separation drum includes a magnetized rim that can lift ferrous objects but not tie plates from the endless conveyor.

Abstract: A railroad cross tie having an inner core with at least one longitudinally extending metallic reinforcing member and an outer casing. The cross tie includes first and second end caps. The first end cap is disposed proximate a first end of the inner core and the second end cap is disposed proximate a second opposite end. One embodiment of the cross tie includes an expansion gap longitudinally disposed between the first and second end caps. Longitudinal dimensions of the expansion gap varies in response to differential thermal expansion between the inner core and the outer casing. In other embodiments, the end caps are mechanically interlocked with the inner core and the outer casing overlays a portion of the end caps. The disclosed structures securely and reliably attach the end caps to the cross tie. A method of manufacturing cross ties is also disclosed.
