Gangway systems
for metros, subways
and suburban railways

HÜBNER gangway systems for metros, subways and suburban railways feature extra-wide passageways, enhanced sound insulation, high flame retardancy and vandalism-resistant interiors. The gangways are individually fitted for the respective vehicle type and consist of a linking ceiling, side walls, and linking bridge. The elastic inner lining compensates for all vehicle motions with a continuous smooth surface.

Flexibility

HÜBNER high-comfort gangways can be customized perfectly for every vehicle type. Customers can select between various surface options. Special gap covers on the linking ceiling and floor connection system make for more safety and more effective sound insulation. The spacious, high-comfort gangways are available in one-piece or two-piece versions with single or double-corrugated bellows.

Design

Individually customized for the vehicle type, the gangway design can function as a single complete gangway element or in two connectible gangway halves. Two-piece gangways are advisable when cars are frequently separated from one another. They can then be flexibly used as dual-direction vehicles.

Coupling technology

The fastening of the vehicle gangways consists of a screw-on frame on the vehicle and a coupling frame as locking element. The material is either welded or curved, powder-coated aluminum profiles. A centering system on the coupling frame ensures simple, problem-free coupling and helps to shorten downtimes.

Whether economical, lightweight single-corrugated bellows or double-corrugated bellows with increased noise insulation – this is for customers to decide in accordance with their particular requirements. Depending on the desired sound and thermal insulation characteristics, different thicknesses in the bellows material and corresponding design are used. For every model type, high-quality materials are used. These feature special characteristics that are indispensable in daily use:

• Flame resistance
• Resistance to cold, heat and UV radiation
• High tear and abrasion resistance

HÜBNER linking bridges absorb all the movements occurring between railway carriages. This makes it so that passengers can pass through the gangway safely and comfortably. The newly developed combi-bridge features a simplified interface together with no-gap and no-step movement compensation. This makes it so that the bridge fits exactly between the end walls of the vehicle. In addition, it is self-supporting and handicapped accessible (TSI PRM). Specially coated bridge plates with low-wear sliding materials ensure a long service life.

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.
