Railway sleeper plates, also known as railway tie plates or base plates are made of mild steel, cast iron, wrought iron or malleable steel and are sandwiched between flat-bottomed rail feet and wooden sleepers to distribute the load over a larger area. Rail sleeper plates are fastened to wooden sleepers by rail spikes or bolts through holes in the rail sleeper plates.
Kingrail Parts can supply ail sleeper plates in various sizes and materials, manufactured according to various international standards such as BS, ASTM and Din etc.
Types of Railway Sleeper Plates

2. Single shoulder railway tie plates
For single-shoulder tie plates, the shoulder is designed at the field end of the plate. The short end or rail gauge end of the plate is placed inside the rail, which is why customers always ask for the width of the rail base. Single shoulder tie plates are typically used for rail weights from 56 lbs to 100 lbs.
3. Double shoulder railway tie plates
We currently use the double shoulder type. The older single shoulder type is available for various rail widths, with the shoulder located on the outside (field side) of the rail.
4. Railroad hook double tie plates
HTTP stands for hook twin tie plate and is widely used for turnouts that sit behind the bottom of the switch. To preserve wire spacing, HTTP often uses a single wire in pairs.

The main role of Railway Sleeper Plates
1. Railway tie plate is used for rail construction, supporting the rail while bearing the rail load and distributing the load to the sleepers
2. The tie plate increases the bearing area and maintains the correct rail gauge of the rail
3. The sleeper plate can prevent the sleeper from being damaged by friction and firmly fix the spikes on the sleeper
