The function of the rail sleeper is to support the steel rail, transmit the pressure from the steel rail to the track bed, and also maintain the position and gauge of the steel rail. Railway sleepers can be divided into two types, namely wooden sleepers and reinforced concrete sleepers. Wooden sleepers have good elasticity, light weight, convenient laying and replacement, but consume wood and have a short service life. Reinforced concrete sleepers have long service life, high stability, and low maintenance workload. The length of railway sleepers is generally 2.5 m.
Due to the longitudinal effect of the rail anchor when the train is running, the steel rail even drives the sleeper to move longitudinally. This phenomenon is called line crawling.
Therefore, in the safe transportation of railways, only by understanding the roles of different track parts and applying them in railway construction can we ensure the safety of our assembly.
