Railroad spikes are used to insert the bottom of the rail into the hole on the sleeper, and then drive the spikes in to tightly fit the rail and the sleeper, preventing the rail from moving horizontally or vertically when the train passes. This is crucial to ensure railway driving safety, because if the rail moves, it may cause accidents such as derailment. When using, the spikes are also used in conjunction with other components such as pads and rail fasteners to ensure the long-term stability of the railway track.
Materials of railway spikes
There are usually several different types of railroad spikes. According to their shapes and uses, they can be divided into round-headed railroad spikes, flat-headed railroad spikes, etc., which are suitable for different railway systems.
Carbon steel spikes:
This is the most traditional material for railway spikes, with low cost and wide use. It is generally suitable for ordinary railways, especially in environments without high strength requirements.
Alloy steel spikes:
In order to improve the strength and wear resistance of the spikes, some spikes use alloy steel, such as steel containing molybdenum, chromium and other elements, which can better cope with high loads and harsh climatic conditions.
