Switch & Crossing
You are here:
Overview
Switches and crossings (S&C) are critical components of railway infrastructure, enabling trains to move from one track to another and safely navigate track intersections.
Key Components
- Switch: Mechanism that guides trains from one track to another.
- Crossing: Allows wheels to pass over intersecting rails.
- Frog: Intersection point where tracks cross.
- Point Blades: Movable rails that direct train wheels onto different tracks.
Functions
- Track Diversion: Enables trains to switch tracks smoothly.
- Safe Navigation: Ensures trains pass intersections without derailment.
- Operational Flexibility: Allows complex rail network management.
Applications
- Railway junctions
- High-speed train networks
- Urban transit systems
