Structure and composition of rail

Rails are components used to withstand gravity and provide guidance on the tracks of vehicles such as railways and trams. It usually consists of the following parts:

1. Rail Head: Located at the top of the track, it is the outermost part of the rail. The rail head provides the contact surface of the train wheels and is responsible for carrying the load of the wheels.

2. Rail waist (Web) : the part connected to both sides of the head, usually shaped I or H. The rail waist plays the role of connection and support in the whole rail structure.

3. Base: located at the bottom of the rail waist and in contact with the track bed. The base installs the rail firmly on the track bed by fixing bolts or other connections.

4. Foot: The part located below the rail base and in contact with the track bed. The main function of the feet is to increase the contact area between the rail and the track bed and disperse the load.

Rails are usually made of high-strength alloy steel to withstand the weight of the train and the dynamic loads generated during operation. Its structure and composition enable the rail to withstand heavy loads and remain stable, thus ensuring the safety and efficiency of rail transport.
