Barrier-free local public transport in Darmstadt

fisco ramp systems and fischer fixing technology in use

Barrier-free local public transport in Darmstadt

HEAG mobilo GmbH is modernising the tram network in Darmstadt. The aim is to provide convenient, low-step boarding and alighting for all passengers. Instead of costly complete conversions, the transport company is relying on partial platform heightening.

63 modular ramp systems made of glass-fibre-reinforced plastic (GRP) from fisco are being used. They reduce the boarding height by five centimetres. Secure anchoring in the substrate is ensured by fischer UltraCut FBS II concrete screws made of stainless steel.

High accessibility requirements

Darmstadt is an important centre for science and business. Around 76,500 people commute to the city every day. Accessible local public transport is essential. Low-step entry helps wheelchair users and people with walking aids. Families with pushchairs and travellers with heavy luggage also benefit.

Most HEAG mobilo stops are already considered low-barrier. Nevertheless, a step of around five centimetres remained at many stations. Many platforms date back to the 1990s. Substrates, materials and gradients vary greatly. Completely rebuilding the stops would have been very expensive and would have blocked rail traffic for months.

Partial platform elevation with GRP ramps

The structural adaptation is carried out specifically in the boarding area of low-floor trains. fischer subsidiary fisco developed precisely fitting ramp systems made of glass-fibre-reinforced plastic for this purpose. 

Precisely fitting dimensions: Depending on the stop, installation depths of 57 cm or 84 cm are available. The standard length is 4.60 m. A 5.80 m long version is available for combined bus and rail stops.

Low weight: One element weighs less than 11 kg. Installation can be carried out by hand without heavy lifting equipment. This saves valuable time.

High safety: The surface meets slip resistance class R13. A flat leading edge prevents trip hazards. Wheelchairs and pushchairs can roll over it effortlessly.

Robust material: GRP is extremely durable, weather-resistant, UV-resistant and non-conductive. The yellow signal colour ensures good visibility.

Compensation for unevenness: The system reliably compensates for slopes and unevenness in the substrate. The ramps remain permanently stable.

Adaptability and practical relevance
Every stop comes with its own specific conditions. Against this backdrop in particular, our modular ramp system and the fastening solution used prove to be especially practical.

Secure hold with the fischer concrete screw UltraCut FBS II

fischer concrete screws UltraCut FBS II made of stainless steel ensure a firm hold. They offer clear advantages outdoors.

Stainless steel: The material permanently withstands moisture, frost and road salt.

Secure hold: The thread cuts into the concrete with a positive fit. This avoids expansion pressure and allows for small edge distances.

Fast installation: The screw is driven directly into place without a plug. This saves time per fixing point.

 

Long-term testing and results

Installation was preceded by an extensive test phase. As early as 2022, HEAG mobilo tested ramps from fisco on its route network. Passenger surveys gave top marks for comfort, safety and visibility. The components also proved to be wear-resistant and low-maintenance throughout all seasons.

With the project in Darmstadt, fisco is setting another milestone in infrastructure development. Previously, 67 platform height increases were completed in Jena, as well as 81 kerb height increases in Kassel.
