Product overview / System solutions
HÜBNER gangway systems for high-speed trains fulfill the highest standards and offer outstanding advantages thanks to advanced engineering and in-house manufacture of key materials.
Corrugated bellows for gangway systems
Corrugated bellows serve as the central connecting element between cars. They ensure a secure, flexible and highly durable inter-car connection under varying operational conditions.
The corrugated bellows feature a high-strength design that is weather-resistant and built for long-term use in passenger service. For high-speed train applications, pressure-tight configurations are used to withstand demanding aerodynamic pressure loads.
All materials meet applicable fire-safety standards (e.g. EN 45545 HL1–HL3, NFPA 130, etc.).
Depending on the technical demands, the corrugated bellows may have a single layer (single corrugated bellows) or a double layer (double corrugated bellows).
Single corrugated bellows: Compact design, low weight, cost-efficient solution
Double corrugated bellows: For more demanding requirements in acoustic and thermal insulation
Attachment systems
The corrugated bellows may be attached to the car body either via a bolted frame or a coupling frame.
Bolted frame: A simple, robust solution for standard applications
Coupling frame: Facilitates fast disconnection or replacement; the corrugated bellows can be detached with a few manual steps
For high-speed operation, both attachment systems can be provided with integrated sealing and pressure-tight capability. Additional sealing measures are therefore not necessary during installation of the corrugated bellows.
Bridge systems
Various bridge systems are available to ensure safe and comfortable passage between cars. They are all compliant with EU TSI PRM accessibility standards and can be customized for different vehicle designs.
Bridge plates: Compact and robust solution for basic requirements and limited installation space. Equipped with low-friction materials for long-service life.
Linking bridges: An enhanced design for more comfort and easier maintenance. The hinged design allows for quick maintenance access and provides gap-free, reliable compensation even for extreme vehicle movements.
Combi-bridges: Self-supporting, flexible, and efficient: Combi-bridges adapt to virtually any vehicle movement. They combine outstanding technical performance with a high level of comfort and can be customized with various floor coverings to meet specific customer and project requirements.
Tread plates: Developed specifically for vehicles with Jacobs bogies. They minimize height offsets and ensure a safe, continuous transition between cars.
Patented HÜBNER wind fairing system
The aerodynamic fairing with its rectangular/box-shaped configuration is a proprietary design solution of the HÜBNER Group. Acting as an aerodynamic shroud, it provides a seamless connection with the car body contour and reduces air resistance. This can result in energy savings of up to 4% – an innovation that makes it possible for high-speed trains to operate more efficiently and sustainably around the world.
Product benefits & technology
Smooth, nearly flat surface: No visible seams at the corners and box-shaped bellows configuration.
Energy efficiency: The fairing reduces drag and helps to lower operating costs.
Noise reduction: Closed bellows and wind fairing systems reduce interior noise levels by up to 40 dB.
