2-metre-high transparent screen with Hammerglass safety glass on a pedestrian bridge over railway tracks, Stavanger station.

”Glass railing failed. A man fell more than 8 meters onto the railway track.”

This headline could be read in Norwegian newspapers on 30 March 2025. A 21-year-old man leaned against the glass railing on the bridge spanning the railway tracks in central Stavanger. The tempered glass gave way, and the man fell freely 8–10 meters (!) onto the railway tracks below. The time was 03:45 on Sunday morning, and fortunately no trains were operating at that time. The man miraculously survived.

As a result of the accident, an extensive planning process was initiated to replace the 150-meter-long glass railing, which for around 30 years had protected passers-by from falls and live overhead contact lines. SWECO was assigned the design responsibility and developed, during spring 2025, a proposal for a safe and transparent solution. In cooperation with HMG iNFRA, a 12 mm specially coated Hammerglass polycarbonate system was selected. The existing mounting system in slim posts with four glass clamps per panel was retained, but all fixing components were replaced with new stainless-steel solutions. The moss-covered wall coping was to be cleaned, and the top edge fitted with a 3 mm thick, grey-lacquered aluminium sheet.

Rain, snow and strong winds

In March 2026, with wind speeds up to 21 m/s, snow and heavy rain, HMG iNFRA’s Swedish installation team replaced the tempered glass in the Norwegian coastal city with high-performance polycarbonate. 

 

The two-metre-wide Hammerglass panels weighed around 50 kg each, and there was no room for lifting equipment on the pedestrian bridge over the railway tracks. Strong winds, rain and cold made handling the panels extremely challenging.

 

– It was a tough job, says HMG iNFRA’s installation manager Daniel Ragnarsson. Because of the limited space, we had to lift the panels by hand and then press in a glazing seal before securing everything in the clamps. This would never have been possible if the panels had been made of tempered glass, which weighs at least twice as much as polycarbonate.

 

Due to the train traffic, work was only allowed for 2.5 hours each night on the section of the bridge located directly above the railway tracks, and it was essential that nothing stalled. Despite careful preparation and measurements, the site conditions still turned out not to fully match expectations when installing the 73 new safetyscreens.

 

– We were in Stavanger already in January to take measurements, but when we returned for installation, the height of the coping plate mounted on the wall didn’t quite match. All the Hammerglass panels had been manufactured to exact dimensions, but we still had to make adjustments on site.

 

After three days and three nights of installation, the completed barrier now stands in place as a safe protection on the bridge over the track area, ready to safeguard passers-by against fall risk and the live overhead power lines above the tracks. The client, Stavanger Parkering, was very satisfied with how the installation and the unforeseen issues were handled along the way.

 

– Extremely friendly and skilled installers you have, and the Hammerglass panels look very elegant!😊 (Project manager Øyvind Helgeland, Stavanger Parkering)
