The upgrade involved the use of a new style of system for the Country Regional Network; the Bodan Panel Level Crossing System. Bodan is a modular style panel level crossing system that transfers the traffic loads of the road by frameless concrete panels through the rail sleeper and into the ballast bed below. The panels are constructed from polymer concrete and all precast prior to coming to site. The system is put together on-site with various components coming together to form a large level crossing system. The crossing at Rydal was a single line crossing and due to the shape of the road, the panels were able to accommodate the crossing with a staggered design. The system has been used in 20 countries around the world, including Austria, Germany and Japan.
Rydal presented a short possession timeframe for the work to be completed. Therefore, to ensure the work could in fact be completed, a TWA arrangement for safe working was undertaken to extend the possession. The flexibility of the panels and the TWA meant work could be undertaken with little interruption from rail traffic. The TWA arrangement prevented long windows of time being lost to TOA style safe working arrangements. The panels allowed quicker install than a concrete in situ option and instantly provided a sturdy level crossing with no concrete dry time.
A temporary bypass road was constructed on-site to ensure local traffic could still flow through the area. This was important due to the work occurring in a small town where an alternative detour was lengthy. Due to the temporary detour road constructed on-site, this resulted in a tight area for plant and people to traverse in. Plant and people separation was carefully thought out and executed on-site to ensure safety was paramount.
