The rails of the high iron welded together as a whole
An interface is not seen, like two complete rails, one to the end. Such high precision technology can ensure the stability of the road.
After laying high speed rail, the technicians will use advanced welding technology to carry out two welding and grinding between the rails. A length of 500 meters, weighing 30 tons of rail welded into an ultra long seamless line, to achieve a track shop in the end. A flexible joint is arranged at the expansion joint, and the expansion space provided with the heating is reserved.
Seamless welding technology, can make between two rails almost can not see the welding point, natural transition, in the high-speed rail, "bang" sound will become history.
