The cross section shape of the track rails adopts H-shape cross section, which has the best bending performance. And it consists of the rail head, rail web and rail foot three parts. To enable the rail to better support forces from all aspects, to ensure the necessary strength conditions, rail should be in sufficient height, the head and the bottom should be in sufficient size and height, waist and bottom should not be too thin.
Among these types of steel rails, 38kg / m rail now ceased production, 60kg / m, 50kg / m railway rails are laid on the main trunk line, station and dedicated lines are generally laid with 43kg / m rail. For heavy rail and particularly busy railway sector, it laid with 75kg / m rail.
In addition, in order to meet the needs of turnout, large bridge and seamless lines and other structures, China railway railway also uses special section (with the axis of asymmetric-shaped) rail. Now the rail with short special sections, AT rails short, are used more,
