What are the 2 main types of rail spikes

. Due to differences in structural design, each type is suited to specific sleeper scenarios and operational requirements, together ensuring the reliable fastening of the track base.

feature an "L-shaped head + smooth shank" design. The head directly contacts the top of the rail base, and the shank is hammered into wooden sleepers. Fixation relies on the compressive friction of the sleeper fibers, firmly locking the rail in place and preventing lateral movement. Dog spikes are simple in structure, easy to install, and cost-effective, making them suitable for wooden sleeper tracks, such as low-traffic branch lines or scenic railways. However, their applicability is limited to wooden sleepers, and their vibration resistance and anti-loosening performance are relatively low.

feature a threaded shank and various head designs (square, hexagonal, etc.) and are typically used with embedded sleeves, spring washers, and other accessories. The threaded design allows secure engagement with embedded sleeves in concrete sleepers. Installation is performed with a torque wrench, and the thread provides long-lasting gripping force. Additional anchoring materials, such as sulfur or resin, can further enhance fixation. Screw spikes offer superior pull-out resistance and fatigue performance compared to dog spikes and are widely used on high-speed railways, freight lines, and urban transit systems with concrete sleepers.
