Pandrol says its fastenings are in use on two of China’s recently completed high speed dedicated passenger links. The two lines have commenced operations with top speeds of 155 mph; increases to 185 miles per hour are planned.
The first line is now in operation between Shijiazhuang and Taiyuan, a distance of 118 miles. This line is comprised of 47.2 miles of track, 24.23 miles of bridges, and 46.6 miles of tunnels. The ballasted tracks are equipped with Pandrol Fastclip rail fastenings.
The second line is 222 miles in length and in operation between Hefei and Wuhan. There are four main tunnels on this line, Dabieshan Tunnel (8.24 miles); Jinzhai Tunnel (6.65 miles); Hongshiyan Tunnel (4.88 miles); and Hongshigen Tunnel (3.17 miles). Pandrol In-line SFC fastenings were selected to be installed in the tunnels in this project, once again selected for the lateral (up to ±12mm) and vertical (+30/-0mm) adjustment they offered.
Pandrol’s Offset SFC (Single Fastclip) baseplate system is used throughout the tunnel sections. These baseplates, incorporating the Fastclip fastening, feature lateral adjustment of up to ±12mm, and vertical adjustment of +30/-2mm, which makes it appropriate for slab track where the speed and ease of installation and alignment, both in the initial construction and subsequent realignment, is critical.
