What is the difference between tie plates and mending plates?

Tie Plates

Definition: Tie plates, also known as connecting plates or steel rail pads, are specifically designed for use in railway systems.

Function: They serve to secure and stabilize the rails to the sleepers (ties), ensuring that the tracks remain aligned and secure under the weight and movement of trains.

Material: Tie plates are typically made from durable materials such as steel, capable of withstanding the constant stress and wear from train traffic.

Placement: They are placed underneath the rails and attached to the sleepers, creating a sturdy foundation for the railway tracks.

Mending Plates

Definition: Mending plates are general-purpose plates used for repairing or reinforcing structures, particularly in the context of woodworking, carpentry, or structural engineering.

Function: They are employed to mend broken or weakened parts of a structure by providing additional support and stability. In woodworking, for example, mending plates might be used to reinforce joints or fix cracked or split wood.

Material: Mending plates can be made from various materials, including galvanized steel, which provides corrosion resistance and durability.

Placement: They are attached to the damaged or weakened area of the structure, often using screws, nails, or other fasteners, to reinforce and restore strength.
