Alstom's concrete rail track gets German approval

2 Dec 16 The German rail authority has approved Alstom’s concrete slab track system for both high-speed and conventional rail services.

The non-ballast system, NBT, has been developed for mixed traffic at a maximum operational speed of 360 km/h.

Eisenbahn-Bundesamt (EBA) has classified NBT as “Zulassung zur Betriebserprobung” – “approved for operating testing”.

Key players in the German rail community have worked closely with Alstom to obtain the approval: TÜV Rheinland InterTraffic, ACR and the Technical University of Munich (TUM).

Alstom co-developed NBT for main-line owners seeking a concrete track. NBT has an design inspired by concrete pavement experience. The construction process is derived from the service-proven Appitrack technology, which allows construction rates of 300m of track per day and is said to reduce the track-laying schedule by 40%.
