Advantages

Stabirail is changing the world of Rail Construction & Engineering. Its revolutionary method for laying slab track leaves more room for design and functionality.

The boundaries for rail construction and engineering seemed to be set in stone for a very long time. Stabirail has been taking down these boundaries one by one with its new and ground-breaking method for laying slab track.

Compared to traditional rail construction, Stabirail has designed and developed a unique method for milling concrete blocks which ensures the rails can be assembled accurately and directly on the concrete. This guarantees, among many other advantages, faster construction times at lower costs.

Advantages of Slab Track by Stabirail

  • Fast working method: This new technology has proven to be the most efficient solution
  • 2mm accuracy: The Stabirail system is operated by a 3D system, which allows for the highest accuracy
  • Reduced vibration to the tunnel construction and buildings above: Vibrations caused by passing trains do not pass to the adjacent structures when riding over slab track
  • Shallow construction height of the tunnel: Slab track systems require less construction height than their ballasted counterparts. This is advantageous in tunnels where headroom is limited
  • Reduced dead load: The reduced construction height means reduced dead load
  • Higher speed operation: Higher running speeds are achievable due to a greater degree of stability of the track bed
  • Very low maintenance requirements: There are numerous examples of slab track installations where little or no maintenance has been carried out for over the last 25 years
  • Long design life: A concrete slab track is constructed with a design life of at least 60 years
  • Low whole-life cost: Slab track systems have proven their whole-life cost is lower than that of traditional ballasted track

Slab track railroad construction on bridges

Longitudinal movement is one of the most commonly encountered problems when laying slab track on bridges. In traditional “top down” methods for laying slab track, the rails are put in place first. Afterwards – when pouring concrete – the total weight of the construction is increased many fold. This increase in weight will cause the bridge to sag, which will eventually cause longitudinal movement of the train rails.

Stabirail’s new and improved “bottom up”-method for laying slab track avoids longitudinal movement all together. Because the concrete is poured before the rails are put in place, no sagging and therefor no longitudinal movement will take place.

Slab track railway construction in tunnels

Because the underground in tunnels is usually stiff and stable, a tunnel is the perfect location for slab track railroad construction. The application of slab track in tunnels is very efficient in terms of railway construction, durability, strength and costs.

Using Stabirails new and improved “top down” method for railroad construction, slab track can be assembled directly on the concrete bed, thus reducing dead load. Our railway construction train is operated by a state-of-the-art 3D system, which allows for 2mm accuracy.
