Dog Spikes Overview
Dog spikes, also known as screw spikes or coach screws, are essential components in railway track construction. They are used to secure rails to the underlying wooden or concrete sleepers, ensuring stability and alignment in the rail system.
Functions
Securing Rails
The primary function of dog spikes is to firmly secure rails to sleepers, preventing lateral movement and maintaining proper alignment.
Resistance to Forces
Dog spikes must withstand the dynamic forces generated by moving trains, including vibrations and impacts, to maintain the stability of the rail infrastructure.
Ease of Installation
The design of dog spikes allows for relatively easy installation using specialized tools. They are driven into the sleeper and rail baseplate during track construction or maintenance.
Maintenance
Dog spikes contribute to the overall low-maintenance requirements of rail tracks. Their durability reduces the frequency of replacements and ensures long-term reliability.
