Also known as the sleeper plate circuit. It is a prestressed concrete sleeper plate, which is laid in a compacted bed, and the wires are filled with asphalt or other materials. The prestressed concrete sleeper plate is 55cm wide and twice as wide as the normal prestressed concrete sleeper, with the same length and thickness as the ordinary prestressed concrete sleeper (see color map). Therefore, the contact area between the wide sleeper and the daoist bed doubles the contact area between the normal sleeper and the daoist bed, thus reducing the pressure on the bed
The traffic order of the passenger train without stop-point on the road may be issued by the relevant railway bureau directly to the terminals of the two terminals, the traffic (train) section.
