[0002] The sleeper, also known as the sleeper, is also a kind of railway accessories. However, the materials used now are not only wood, so it is more scientific to call it a sleeper. Although the sleeper looks monotonous and unremarkable, it plays a significant role. The sleeper not only supports the rails, but also maintains the position of the rails, and also transfers the huge pressure transmitted by the rails to the roadbed. It must have a certain degree of flexibility and elasticity, and it will not work if it is too hard or too soft. When a train passes by, it can be deformed appropriately to buffer the pressure, but it must be restored to its original state as much as possible after the train passes.
