A base plate, which is made of plastic and is intended for supporting a rail for a rail vehicle on a substrate, include a lower face, and an upper face on which a supporting surface for the rail is formed, a recess, from which a passage leads to the upper face of the base plate, being formed in the lower face of the base plate, the diameter of the recess in a direction transverse to the longitudinal axis of the passage being greater at least in part than the diameter of the passage, so that a stop for an insert piece fitted into the recess is formed on the top surface assigned to the upper face of the base plate of the recess.

The tie plates, normally, made of steel, have a wrap-around device that gives additional support. The wrap-around device goes around or partially the tie and takes various forms as such. It may be a U-shaped bracket with the top section welded to the tie plate. The vertical legs extend beyond the bottom of the tie and have a bolt between the bottoms of the legs. The brackets may be further secured to the tie by lag screws. The tie plate would still have conventional spikes. In another embodiment, it may be shaped as a metal box that is attached to the tie plate by welding with bolts or lag screws in the sides of the box. The design of these devices transfers weight vertically as well as sideways from the wheels. If the ties are made of concrete, the box design allows the concrete to flow therethrough.

A plating system for attaching a pair of tie plates to a wooden railroad tie with screw spikes such that the tie plates are aligned and in gauge. A predrilling system is used to predrill holes in the appropriate position on the railroad tie according to the line end of the tie prior to loading the tie into the plating system. The plating system clamps the railroad tie in registration according to the line end of the tie, and holds the tie plates in the appropriate position while a pair of hydraulic screw-presses turn screw spikes to fasten the tie plates to the railroad tie in gauge, centered and aligned on the railroad tie.

A tie having a non-linear keyway under the overlying rail to provide support to restrain lateral and longitudinal movement of the rail. A fastening system to hold rails down on a tie comprises a rail plate that may be fastened to the tie within the keyway. The fasteners are protected to avoid damage in case of a derailment or other adverse conditions. Also disclosed are visual inspection mechanisms to assist with determining whether a fastening system is securely attached to the tie.

A railroad tie plate has a generally prismatic body including a field side flange and a gauge side flange connected by an intermediate portion. The intermediate portion includes a rail seat for positioning a railroad rail. At least one of the flanges includes a protrusion extending in a thickness dimension of the tie plate. A hole extends into the at least one protrusion so as to receive a retaining device, such as an e-clip. The tie plate is made by hot forging, having a microstructure comprising pearlite and alpha-ferrite. The net shape of the tie plate may be achieved by forging without subsequent material addition and without subsequent material removal.
