In the 1990s, Hübner introduced a unique system of flexible gangway side walls to the market. These side walls continue to provide a flexible connection between carriages, increasing the available comfort zone in the gangways. The walls cover the bellows, providing a noise absorption effect and completely avoiding any exposure of moving edges in the train interior. The flexible side wall arches and extends to accommodate vehicle movements. In addition to these benefits, the highly vandalism-resistant inner lining is readily adaptable to nearly every vehicle type.
Flexible side walls – Folding bellows with inner lining
The inner lining – consisting of a linking ceiling, side walls and linking bridge or bridge plates – provides a flexible connection between the carriages and increases the available comfort zone in the gangway. In addition to the functional requirements fulfilled by these side walls, the highly vandalism-resistant inner lining can be customized to fit the interior design of all kinds of different vehicles through a wide selection of different surface options.
Flexible side walls cover the corrugated bellows and are so pliable that they adjust to the different movements of the vehicle as it is in motion. Moving edges in the interior area are avoided completely. The inner lining of the comfort gangway also has a positive effect on sound insulation.
Rollable side walls – Large passageway width
With a new enhancement of the inner lining, it is possible to maintain all the advantages of the flexible side walls and to eliminate the arching in the gangway through the new rollability feature.
This provides an entirely flat surface in the high-comfort gangway area.
This new rollable side wall does cause a slight reduction of the clear passage while providing more space and lower weight. The rollable model allows for individual color selection, the option of painted surface or the application of a decorative foil.
