Increasing the rail length and weight
|
Since 1995, axial force rail solution and buckling resistance technology have been applied to
the steel plate railway girder bridge and sharp curves under R600, where 20M standard rail
was laid to increase the length of rails to more than 200M, used heavier rails of 60KG/M. |

Direct Fixations Fastening Systems for Stations |
The structures of peony tree ties in the station, where fastening and bearing capacity have
deteriorated due to a long service, and the RC peony landfill track structure, which lacks shock
absorption,have been improved by restructuring them in a direct-coupled structure. |
