FU Synthetic Railway Sleeper use case by the Nanakuma Line of Fukuoka City Subway in Japan that runs with linear motor technology.

Due to the large number of steep slopes and curves on this route, the Nanakuma Line uses a steel wheel linear motor train system. This system allows it to use smaller cars and smaller tunnels, which results in the reduction of construction expenses.

Since the linear motor train requires a strict interface to reaction plates, FFU Synthetic Railway Sleeper was applied for the turnout section so that track construction and maintenance engineers can easily adjust the positioning at the site.

FFU Sleepers comply with the EU regulation about fire, it is a very important point when you want to consider when installing sleepers in a tunnel. Not all sleepers are permitted. On the other hand, FFU sleepers have an elasticity that extends life and reduces turnout maintenance.
