Alstom has received recognition from the German railway federal authority Eisenbahn-Bundesamt (EBA) for NBT, its concrete slab track solution for high-speed and conventional rail systems. The EBA classified NBT as “Zulassung zur Betriebserprobung”, meaning “Approved for operating testing”.
This non-ballast track solution has been developed for mixed traffic at a maximum operational speed of 360 km/h. Alstom co-developed NBT for main-line owners seeking a concrete track, i.e. a railway track with extensive lifespan and high infrastructure availability, which can be installed faster than traditional slab track, and be operated for mixed traffic (both passenger-dedicated and freight transport). NBT has an innovative slab design inspired from concrete pavement experience. The construction process is derived from the service-proven Appitrack technology which allows higher construction rates with 300 m of track laid per day and schedule of track laying reduced by 40%.
The EBA is recognised worldwide for its experience in the slab track homologation, which is carried-out in the past 40 years on the German high speed railway network.
