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.

Main Functions:
1. Tie Plate plate is used in rail construction to support the rails, and also to take the load of rail and distribute the load to the sleepers;
2. The railroad plate increases bearing area and holds the rail to correct gauge;
3. The railroad plate prevents damage of the sleepers due to rubbing action and holds the spike firmly to the sleepers.
