Rail Iron Plate
The railway tie plate, which also can be called as railway base plate or sole plate, is made of either mild steel, cast iron, wrought iron, or malleable steel, it's interposed between the foot of a flat footed rail and wooden sleeper to distribute the load on a larger area.

The railway tie plate is fastened to wooden ties by means of rail spikes or bolts through holes in the railway tie plate. The part of the plate under the rail base is tapered, setting the cant of the rail, an inward rotation from the vertical. The top surface of the plate has one or two shoulders that fit against the edges of the base of the rail.
Railway Pad
A rail pad, also called rail rubber plate, is designed between the rail tie plate and foot of the rail, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting.

It's always fastened within a fastening system by screw spikes or rail bolts into the sleeper ties. The reason why rail pad made up of rubber or plastic is to dampen the shocks or vibration of a passing train.
