Rail track is an essential component of rail track, and its function is to guide the train wheels moving forward by withstanding the enormous pressure pushed by the wheels. Steel rail shall provide smooth, stable and continuous rolling surface for the passing train wheels. In electrical railway or automatic block section, railway track can also be used as track circuit.
The composition of steel rail
Heavier train and fast speed requires higher requirements to withstand stresses, so they are produced from high carbon steel (carbon -0.6 % to 0.8 %, manganese 0.8%-1.3 %, silicon 0.1 % -0.5 %, sulphur and phosphorus0. 03 % maximum each, and aluminum 0.015 % maximum).
