Spring Rail Switches
Spring Rail Switches
Switches made from a specific asymmetrical or symmetrical tongue rail section are forged at the end to match the standard rail section and are electrically flash-butt welded to the adjacent standard rail.
The weld is located in the flexible-elastic area of the switch and is secured with safety fishplates. A flexible area can be provided for in the standard rails to reduce the setting forces.
Advantages
- Proven and low-cost design
- Low setting forces
- High wear reserves
- Little maintenance work
