Berlin commuters have a new transport option from Monday, as the long-awaited S15 S-Bahn line officially begins passenger service just before midday. Running between Gesundbrunnen and Berlin’s central station every ten minutes, the route promises shorter journeys and easier connections – particularly for those travelling from the north of the city. Around 40,000 passengers are expected to use the line each day. But the launch also brings renewed attention to the long delays the project has faced, as well as the time still required to
complete the wider north–south route planned for the future. A quicker, more direct connection In practical terms, the S15 is a short line – but a useful one. Trains shuttle between Gesundbrunnen, Wedding and Hauptbahnhof, with services running every ten minutes throughout the day. Crucially, the journey between Gesundbrunnen and Hauptbahnhof now takes around five to six minutes, cutting travel times by roughly ten minutes compared to previous routes. This means faster access to long-distance trains at Hauptbahnhof, as well as a more convenient link
to Berlin’s airport as passengers from the north-west can now change at the central station instead of making more complicated journeys.

At Hauptbahnhof, passengers on the new service will initially use a temporary underground platform connected to the main building via a pedestrian bridge. Years behind schedule
While the opening marks an important milestone, it comes significantly later than originally planned. The S15 was initially scheduled to launch as far back as 2017, but a series of challenges repeatedly delayed the project. Construction complexities, evolving safety requirements and lengthy approval procedures all played a role. More recently, wider factors such as the Covid-19 pandemic, material shortages and staffing issues added further complications. Even after construction was largely complete, final certification and acceptance processes took longer than expected. READ ALSO: Berlin prepares to
open its newest (and shortest) S-Bahn connection The S15 is only the first piece of a far more ambitious concept – the so‑called S21 north–south corridor. In the coming phases, the line is due to extend further south, first to Potsdamer Platz and eventually to Yorckstraße and Südkreuz. But passengers should not expect these developments any time soon. Current projections suggest the next major extension could arrive in the mid-to-late 2030s, with the complete north–south route potentially not finished until the 2040s. For now, the
S15 offers a faster, simpler journey for thousands of commuters – and a glimpse of a much larger project still slowly taking shape.
