Thanks to continuous further development by PORR, the system, which has been successfully used in long-distance transport since 1989, could also be adapted to the requirements of metro projects. The key element is the Metro track support slab, an elastically supported slab fitted for metro requirements. Built on concrete base it offers logistical and qualitative for construction in tunnels, on viaducts and earthworks.
Since 2016, the Austria ballastless track system for the metro has also been used on a 165 km long section of the Doha metro in Qatar.
Derailment protection is provided in the form of integrated concrete upstands along the full length of the panel. This feature optimizes installation time and cost, as no additional installation of guide rails is required.
Mass Spring System
The standard Metro slab is already a light mass spring-system due to the integrated elastic layer. It can also be implemented as medium and heavy mass spring system when needed.
The key element of the Slab Track Austria Metro system is a prefabricated panel produced under controlled factory conditions, ensuring high quality throughout the production process.
