What Is The Functions Of Railroad Tie Plate?

Railroad tie plates function to support and secure the rails by distributing the vertical load from the rails to the ties, preventing the rail from cutting into the tie, maintaining the correct gauge, and preventing lateral movement. They provide a stable, flat bearing surface for the rail, reduce wear on the ties, and hold the rail spikes or bolts firmly.

Key functions of railroad tie plates

• Load distribution: The plates spread the weight of the train from the narrow base of the steel rail over a larger area of the tie, which helps prevent damage and prolongs the life of the tie, particularly for wooden ones.

• Rail and tie protection: They create a barrier between the rail and the tie to prevent the rail from cutting into the wood or concrete, and to reduce friction and wear.

• Maintaining gauge: Tie plates hold the rails to a constant and correct "gauge" (distance between the two rails), which is critical for the safe passage of trains.

• Preventing movement: They help to prevent the rails from moving laterally and can hold spikes or bolts firmly in place, securing the entire track system to the ties.

• Providing proper cant: Tie plates can be designed with a slight incline, or "cant," to ensure proper contact and load distribution on the top of the rail head.

Rail tie plate between the rail and rail sleeper is one of the important parts of the track structure, and it plays an important damping effect in the wheel/rail dynamic system. With the development of heavy haul railway and increasing axle load, the performance of rail tie plate must be also improved to meet higher requirements in aspects of damping property, impacting resistance and long service life.

Rail tie plate is a fastening device used between rail and rail sleeper. GNEE RAIL has developed and produced the nodular cast iron tie plate.

If you have special requirements for dimensions or higher strength materials, please contact us for special custom production.

Rail tie plates play an important role in securing the safety of railway and passengers. It has the function of supporting the rails and protecting the sleepers. GNEE RAIL can provide you with high quality and reliable rail tie plate and all of our products are inspected by a full set of inspection facilities in quality center. Both standard and customized rail base plates are available according to your drawing and sample.
