Why are they called rail tie plates?
They are called tie plates because they are installed between the steel rail and the railroad ties to "tie" them together and hold the rail to the ties. These plates are a critical component of the railway fastening system, distributing the load from the rail over a larger area of the tie and protecting the tie from wear.
- To "tie" the rail to the tie: The name reflects the primary function of the plate, which is to physically connect and secure the rail to the wooden or concrete tie.
- To distribute the load: The large steel plate spreads the weight of the train from the narrow base of the rail over a greater surface area of the tie, preventing damage and wear.
- To maintain gauge: Tie plates help hold the rails at the correct distance apart (gauge) and prevent the rail from moving sideways.
Types of tie plate
According to the different applications and design, tie plates can be divided into many types, including single shoulder tie plates, double shoulder tie plates and hook twin tie plates.
Single shoulder tie plate
Single shoulder tie plate means the top surface of the tie plate has one shoulder, which can fit the rail base. Single shoulder tie plates are an old kind of tie plate that are not available. Single shoulder tie plate is suitable for almost any rail widths. Most often, rail base width according to requirement. The single shoulder is normally placed on the outside of rail.
Double shoulder tie plate
Compared to single-tie plate, double shoulder tie plates contain two shoulders on the top surface. Double shoulder tie plates are the currently used type. According to the AMREA standard, double shoulder tie plate are available for 5.5in and 6in base rails. Common types include four to eight holes.
Hook twin tie plate
Hook twin tie plates (HTTP) are used for frog, guide rails, and behind the heel of rail switches. There is a slotted hole in the HTTP, which makes it different from other kinds of tie plate. Generally, HTTPs are designed to comply with the AREMA standard and can fit any rail sections. Besides that, the HTTP work in pairs to create a single railroad tie.
