What is a steel rail?
A steel rail is a specially shaped, hot-rolled steel bar forming the backbone of railway tracks, designed to guide train wheels, bear immense loads, and provide a smooth, low-resistance surface for continuous movement. Made from high-carbon steel alloys for strength, hardness, and wear resistance, these inverted 'T' or 'I' shaped profiles transfer train forces to sleepers (ties) and serve as electrical circuits in electrified lines, ensuring safe and steady transport for various vehicles like trains and cranes.
Key Functions & Characteristics
- Guidance: Directs the wheels of locomotives and other rail vehicles.
- Support: Bears the weight and impacts from passing trains.
- Smooth Surface: Offers a continuous, low-resistance path for wheels.
- Electrical Conductor: Can act as a rail circuit in electrified railways.
