| Coating adhesion on wooden articles, such as railroad crossties, is improved through use of three surface-treating techniques prior to application of the coating. The first technique involves forming grooves on the surface of the wooden article, the second technique involves exposing the wooden article to heat to reduce the moisture content of the surface of the wooden article, and the third technique involves creating incisions on the surface of the wooden article to further promote adhesion. The techniques may be advantageously used together to further enhance coating adhesion. | ||||||

| A road transportable concrete railroad long-line tie molding system is described in which a rigid horizontal metal stressing frame is assembled from transportable sub-frame segments. The sub-frame segments are releasably connected in axially aligned end-to-end relation, and include parallel longitudinal reaction members. In a preferred form, the sub-frame segments are convertible from inoperative transport conditions to extended operative conditions. Footings are provided along the stressing frame length to engage the sub-frame segments to releasably mount the sub-frame segments in axial alignment and stabilize the reaction members against lateral deflection during compressive loading. A plurality of conventional gang tie molds having upwardly open elongated mold cavities are releasably received in end-to-end alignment along the framework. A reinforcing wire anchor is provided on the sub-frame at the dead end of the framework and a tensioner is located at the live end of the framework. The tensioner and anchors are adapted to receive and position an array of longitudinal reinforcing wires within the mold cavities. The wires are placed in tension against the reaction members, which react in compression. Both tension and compression forces are isolated from the tie molds. The tensioning forces applied between the tensioner and anchors are distributed about a centroid. The reaction members are positioned in concentricity with the centroid to avoid eccentric loading of the reaction members. | ||||||

| 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. | ||||||
