The Dog Spikes is a crucial component of the railway track system, mainly used to firmly fix the rail on the sleeper and ensure the safe and smooth running of trains.
Common failures include rust (especially in coastal areas), fatigue fracture (due to high-frequency vibration), loosening (aging of sleepers or improper installation), etc. Countermeasures include: selecting weathering steel, applying anti-rust oil regularly, and installing elastic washers to disperse stress. For frozen areas, anti-frost heave spikes can be used. In recent years, composite spikes (such as glass fiber reinforced nylon) have begun to be tested, but their long-term durability still needs to be verified. Failed spikes must be replaced in time, otherwise they may cause track unevenness problems such as "dark pits" and aggravate wheel-rail impact.
