A base tie plate, also called sole plate or baseplate, is a piece of plate made by steel used between the rails and sleeper ties in order to enlarge the bearing touching area and maintain the rail in right gauge all the time. For wooden ties, a baseplate is always fixed with rail spikes or track bolts in holes on the plate
Types of tie plate:
1. The tie plate can be either casting iron or casting steel, depending on the load and the type of rails. Cast iron can be the welded or fabricated type, depending on the customers’ requirements.
2. The double-shoulder type is currently used. Older single-shoulder types were adaptable for various rail widths, with the single shoulder positioned on the outside (field side) of the rails.
