Rail Tie Plate

Rail tie plate is also called rail base plate or sole plate, it is a main component in railroad construction of a crane rail or track support system.

Functions of Rail Tie Plates

Rail tie plates are used not only to support the rails, but also to fix the entire rail fastening systems. It always works together with anchor bolts or spikes by sustaining the load of a rail track and also transferring part of the load to the tie sleepers, with a flat smooth resting surface to guarantee the vertical alignment and hold the rail in correct gauge for a rail line system.

All in all, rail tie plates are used to given a smooth and uniform bearing surface for the rail and the tie in order to prevents the rail from cutting into the tie, maintain gauge, and also helps to better distribute the wheel load to ties.

Agico Rail is capable of producing rail tie plates by either casting(welded or fabricated type) or forging or rolling, applicable of different rail sections, for wooden, steel or concrete sleepers, depending on the load and rail standard, i.e. UIC 60, UIC 54, RN 45, 90 A, etc.

Hook Twin Tie Plate

Or HTTP for short, is a type of tie plate that is used for frog, guide rail, and behind the heel of rail switch. There is slotted hole in the hook twin tie plate, which makes it different from other kinds of tie plate. Generally, hook twin tie plate is designed with AREMA standard and it can fit any rail sections. Besides that, hook tie plate work in pairs to a single railroad tie. The diagram of hook twin tie plate is shown below:

By the types of the hook, hook twin tie plate has three normal types: type L, type LR and type H. Among all AMERA standard hook twin tie plates, 3/4” and 1” thick are two popular types.
