Western extension of Tramway F in Strasbourg: laying tracks on an engineering structure
On the western extension of Strasbourg’s tram line F, ETF teams took on a challenge: laying track with a thickness of only 20 cm on a railway bridge.
A novel technique on a civil engineering structure
Instead of using traditional sleepers and concrete, the rails were directly anchored to the structure using saddles that were glued and fixed with millimetre precision. This delicate work was carried out in a strategic area between a bridge and a curve, where every adjustment was important.
In this type of operation, precision is essential: a weld that is too wide or an anchor that is poorly positioned can weaken the entire structure. Here, the teams demonstrated unique expertise, guaranteeing long-term stability and safety.
Safety and the environment at the heart of the project
Beyond the technical feat, the project was carried out with high standards of safety and quality. The methods used made it possible to preserve the existing structure without damaging its waterproofing.
This responsible approach earned the project VINCI environmental labels (neighbourhood and climate), which recognise the teams’ concrete commitment.
By the end of 2025, the western extension of tram line F will become a reality. This new 4 km section will connect Eckbolsheim and Wolfisheim to the centre of Strasbourg. More than 20,300 residents will benefit from faster, more convenient and more environmentally friendly transport.
