Why are the rails shaped like “I”? – CHINA ROYAL STEEL

meet the stability of trains running at high speeds, match the wheel rims, and best resist deflection deformation. The force exerted by a cross-section train on the rail is mainly the vertical force. An unloaded freight train car has a self-weight of at least 20 tons, and a fully loaded freight train can weigh up to 10,000 tons. With such a large weight and pressure, It is easy for the rail to bend and deform (physical deformation)

During the operation of the train, it mainly contacts the rail head part.On the other hand, it is sufficient for wheel rail wear.
