Berlin's 2026–2028 transport plan prioritises reliability over expansion amid criticism

Berlin's public transport plan for 2026–2028 is now open for public consultation until spring. The draft focuses on stabilising and modernising the existing network rather than expanding it. Officials have made clear that reliability comes before new lines.

The approach has already drawn criticism from politicians disappointed by the lack of growth plans. The guiding principle of the new plan is 'stability before growth'. Instead of adding routes, authorities aim to fix delays, upgrade infrastructure, and maintain current services. Many projects, including underground extensions, have faced years of setbacks, while others now lack firm completion dates.

Since 2023, funding has shifted away from major expansions like the U10 line. Budget limits imposed by Germany's debt brake have forced a focus on smaller upgrades, such as extending the U5 to Mauerpark and improving tram routes in Neukölln. Alternatives like bus rapid transit (BRT), bike highways, and enhanced S-Bahn services are now under consideration for corridors originally earmarked for new U-Bahn lines.

Maintenance depots are already at full capacity, and new vehicles mostly replace old stock rather than increase fleet size. Some tram projects have been pushed back to the 2030s. Officials are even reviewing whether off-peak underground frequencies could be cut to boost rush-hour reliability.

With rising costs, staff shortages, and tight budgets, many long-planned expansions are being reassessed. Authorities are also exploring unconventional solutions, including cable cars or magnetic levitation trains for certain routes. The final version of the transport plan will be decided after the public consultation ends in spring. For now, Berlin's focus remains on fixing the current system before considering major growth. The changes will shape how the city's network operates for years to come.
