Now commonly used railroad spikes include the following types: railroad dog spike, screw spike, spring spike. They are used in different ways, but their effects are the same, that is, through the different structure and use methods, to make rails fixed and stable.
Although the unit price of screw spikes is slightly higher than that of dog spikes, their extended service life and reduced maintenance frequency make them far more cost-effective in the long term. For example, on a standard freight railway line, the use of screw spikes can reduce maintenance costs by about 30%, which translates into annual savings of several thousand RMB per kilometer of track. This advantage is especially valuable for large-scale railway projects where long-term performance and operational efficiency are critical.
