Wedoany.com Report-Jun 3, Implenia, a leading construction company, has been awarded a contract worth over €200 million ($226.9 million) by DB InfraGO, a subsidiary of Germany’s state-owned railway company Deutsche Bahn, to build a section of the Nordmainische S-Bahn beneath central Frankfurt, Germany. The project aims to strengthen public transportation in the Rhine-Main region.

Construction is set to begin in early 2026.

The underground segment will link Konstablerwache in Frankfurt’s city center to Fechenheim, featuring a new S-Bahn station, Frankfurt (Main) Ost (tief). Implenia’s responsibilities include constructing the main construction pit, known as the ‘Trog,’ the pit for the underground station, and several auxiliary pits, along with associated civil engineering structures. The project also involves drilling two 1.2-kilometer tunnel tubes using tunnel boring machines and implementing water management measures.

Given its location in a densely populated urban area, the project requires advanced foundation services to meet sustainable and modern construction standards. Detailed design work is set to conclude by the end of 2025, with construction starting in early 2026 and expected to finish by 2031.

Implenia Civil Engineering head Edwin Scherer stated: “Maintaining and developing a functioning transport infrastructure is central to the sustainable development of our cities. I’m very pleased that Implenia, with its many years of experience and comprehensive expertise, can contribute to the improvement of public transport in the densely populated Rhine-Main region.”

The Nordmainische S-Bahn project is a key investment in Frankfurt’s transportation infrastructure, designed to enhance local transport connections and increase rail capacity in the Frankfurt (Main) hub. It aims to improve reliability and comfort for commuters while supporting environmental goals through reduced carbon emissions, according to Implenia.

Recently, Implenia, in a joint venture with HOCHTIEF, was also commissioned by Deutsche Bahn for the ‘733 Tunnel Ostbahnhof,’ part of the Munich S-Bahn expansion, underscoring its expertise in advancing Germany’s rail network.
