Low track width and height

Modularity and flexibility of Slab Track Austria can be a great advantage in challenging projects. 
Panels can be reduced to 2.1 m width and 43 cm track height from top of the rail enabling installation in conditions with limited space. 
The small dimensions of Slab Track Austria can provide significant savings in situations where old tunnel refurbishment is required. It is possible to avoid tunnel profile extension by simply using Slab Track Austria, thus lowering the height of the system and providing the necessary clearance even when new electrification is necessary. The modernization of Tauern tunnel and Arlberg tunnel are two examples where significant savings could be made by employing Slab Track Austria. 
Optimization and cost effectiveness  
Cross sections of new tunnel can be optimized and significant savings made by taking advantage of the dimensions of the Slab Track Austria. The sleek system, with its low construction height can be used to reduce the tunnel diameter.
Due to its low height the Slab Track Austria is also lighter than conventional ballast track system and other slab track systems. This allows savings in the design of bridges and viaduct structures.
If Slab Track Austria is considered in the early stages of the project design, significant savings can also be achieved in the total bridge construction costs. Due to its low height and comparably low mass, Slab Track Austria is a light system and its implementations results in lower initial investment costs for the bridge construction compared to those required in case traditional ballast track system is used. Additionally, since Slab Track Austria is almost maintenance-free (except for rail grinding), PORR’s system provides maintenance savings advantages throughout the life span of the track system.
