1. How are spikes adapted for light rail systems?
Light rail spikes feature:
Smaller heads (25×25mm)
Softer steel to match rail hardness
Anti-vibration coatings
Low-profile designs
2. What's the history of spike manufacturing?
Timeline:
1825: Hand-forged iron spikes
1860: Machine-cut steel spikes
1920: Heat treatment introduced
2005: Automated CNC production
3. How do you prevent spike theft?
Security measures:
Serial number engraving
GPS-tracked shipments
Tie-plate locking systems
Patrols in vulnerable areas
4. What are the magnetic properties of spikes?
Standard spikes:
Permeability: 300-400 μ
Residual magnetism: <5 gauss
Affects signal systems if exceeding 10 gauss.
5. How are spikes disposed of properly?
Eco-friendly disposal:
Remove from ties
Sort by metal type
Bulk shipment to recyclers
Smelting at 1,600°C for new steel
Landfilling is banned in most countries.
