Rail Dog Spike

Rail dog spike, also known as railway dog spikes or track spike, is a common fastener in the railway fastening system. Rail dog spikes are used to secure rails to the sleepers and used to maintain distance between tracks, ensuring track stability and preventing derailment. The unique design of the rail dog spike makes it widely used in the railway system. The whole shape is L-shaped with a square shank, which enhances the spike’s resistance to pull-out. The bottom of the head of the rail dog spike is inclined to match the shape of the rail edge, which is lower on the sides and higher in the middle. This ensures that the rail dog spike tightly presses against the bottom of the rail, preventing lateral movement of the rail. The tip of the rail dog spike is wedge-shaped rather than pointed. The wedge is driven into the sleeper laterally, parallel to the rail, to prevent longitudinal movement of the rail. Rail dog spikes are usually used with rail tie plates, driven deeply into the sleeper through the holes in the rail tie plate using a hammering method, ensuring a solid structure between the rail and the sleeper.
As a professional manufacturer of railway fastening systems, AGICO not only produces rail dog spikes but also produces other railway fasteners such as elastic rail clips, screw spikes, rail anchor. Rail dog spikes are made of high-quality steel, such as Q235 carbon steel and Q345B carbon steel. Every production process is supervised according to production standards, and every batch of finished products undergoes strict tensile testing and quality inspection. AGICO’s rail dog spikes can be produced according to various standards such as GB, DIN, ISO, ANSI/ASTM, B7, BS, and JIS, meeting the needs of customers in different regions. Customization is available whether it is size, process, or surface coating. Common rail dog spike sizes are 5/8”, 3/8”, 1/2”, and 3/4”. They are usually packed in 200-pound or 50-pound barrels.
