Railroad tie plate, also called base plate or sole plate, is a kind of steel plate used between the rails and sleepers on rail tracks. Tie plate is usually tapered on the sleepers by rail bolts or rail spikes through the holes in the plate. Generally tie plate is usually tapered at each end of rails to ensure the stability and hold the rail to correct gauge. The use of rail tie plates extends the service lifetime of rails and ensures the safety of passengers and railway workers. Whether on wooden sleepers or concrete sleepers, rail tie plates play an irreplaceable function in fastening the rails.

Fasten the Rails and Sleepers

Tie plate is an irreplaceable component in fastening the rails and sleepers, and it provides a solid foundation of the rails and reduces the abrasion damage of the sleepers. With the help of rail spikes and other fastening components, rail tie plates can fix the rail tracks properly and prolong the service life of rails and sleepers.

Keep the Correct Rail Gauge

Consider of the force caused by the weight of passengers and the train, the rail may deviate from the original track slightly. It is tie plates together with sleepers which fasten the rails tightly so that the trains can run safely on the tracks. It is also vital for the railway workers to inspect and repair the railroad regularly, especially for the replacement of rail spikes, tie plates or other fastening accessories after using for a period of time.

Distribute the Weight Forced on the Rail 

Railroad tie plates can evenly distribute the weight of the train, cargo or passengers.
