GAFs For DB Bahnbau Gruppe

posted on 29th Apr 2022 12:39

On 1 December 2021, WINDHOFF has agreed a framework contract with DB Bahnbau Gruppe for the procurement of up to 10 track work vehicles. DB Bahnbau Gruppe GmbH provides construction services for DB AG's railway infrastructure throughout Germany. For these undertakings, it requires appropriate track work vehicles that are characterised by a high degree of flexibility with regard to their performance and the occurring operating conditions.

As part of an EU-wide tendering procedure, DB Bahnbau Gruppe concluded a framework contract with WINDHOFF Bahn- und Anlagentechnik GmbH for track work vehicles (GAF, Gleisarbeitsfahrzeug) at the end of an intensive procurement phase based on various criteria. The first lot includes three GAFs, which will be equipped with an innovative and sustainable working concept. They will be built by WINDHOFF in Rheine and are scheduled for delivery in August 2024.

This is a particularly compact version of the four-axle MPV VentuS vehicle from WINDHOFF's platform. This configured vehicle offers significant added value due to its modular design, which allows its owner selective modifications during the vehicle lifetime to fulfill future requirements. This could be an exchange of the present drive-engine to the engine of the future - whatever it may be - but a replacement of the crane module to e. g. another social container as well.

The electric drive of the GAFs, which is one of the new energy modules of the MPV VentuS platform, has been completed with a high-energy traction battery that allows an emission-free running in working mode and will also respect noise regulations nearby urban settlements. Another special feature is the low axle-load compared to the standard two-axle vehicles, bringing an advantage that the new vehicles can be used on all route classes of the DB network, while at the same time offering better driving dynamics.

While there is a large continuous loading area with a powerful working crane in the area behind the fully air-conditioned cab, all drive and auxiliary units are arranged as modular sub-assemblies under floor. This is optimally suited for the transport of rails, switch parts and sleepers or for carrying the necessary construction materials and tools.
