HEAG mobilo GmbH is modernising the tram network in Darmstadt. The aim is to provide comfortable boarding and alighting with minimal steps for all passengers. Instead of costly complete conversions, the transport company is using partial platform height increases.
63 modular ramp systems made of glass fibre-reinforced plastic (GRP) from fisco are being used. They reduce the boarding height by five centimetres. fischer UltraCut FBS II concrete screws made of stainless steel ensure secure anchoring in the ground.

Darmstadt is an important centre for science and business. Around 76,500 people commute to the city every day. Accessible local transport is indispensable. Low-step access helps wheelchair users and people with walking aids. Families with prams and travellers with heavy luggage also benefit from it.
Most HEAG mobilo stops are already considered to have low barriers. Nevertheless, a step of around five centimetres remained at many stations. Many platforms date back to the 1990s. Substrates, materials and inclines vary greatly. Completely rebuilding the stops would have been very expensive and would have blocked rail traffic for months.

The structural adaptation is carried out specifically in the boarding area of low-floor trains. The 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. For combined bus and train stops, a version with a length of 5.80 m is available.
Low weight: One element weighs less than 11 kg. Installation can be carried out manually without heavy lifting equipment. This saves valuable time.
High safety: The surface meets slip resistance class R13. A flat approach edge prevents tripping hazards. Wheelchairs and prams roll over it effortlessly.
Robust material: GFRP 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 inclines and unevenness in the substrate. The ramps remain permanently stable.

Every station has its own unique circumstances. It is precisely against this backdrop that our modular ramp system and the fastening solution used prove to be particularly practical.
The installation was preceded by an extensive testing phase. From as early as 2022, HEAG mobilo tested fisco ramps across its rail 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 expansion. Previously, 67 platform elevations were completed in Jena, along with 81 kerb elevations in Kassel.
