It all began in March 2018: The contract signing for the extension of the M4 line with Metroselskabet I/S took place in Copenhagen. Exactly 2,280 days later, on June 22, 2024, after years of planning, preparation, and execution, the extension of the metro line was officially inaugurated at Mozarts Plads in Copenhagen by King Frederik X.
Together with our partner Efacec, we were responsible for installing the slab track, the power rail, and the railway equipment. Our international and dedicated project team, especially during the main construction phase, consisted of members from more than ten different nations and once again demonstrated how we at Rhomberg Sersa Rail Group optimally bring together international forces—always to the benefit of our customers.
Now it is time to look back on this project full of collaboration, innovation, dedication, and teamwork.
