As part of the planning work for the 2025 reference concept, it became apparent that supply and rolling stock at the Lucerne junction require adjustments to track occupancy and the exit regime compared to today. Long-distance trains in the 2025 horizon are getting longer and heavier. This has a negative impact on the braking behavior and driving dynamics of these trains. In mixed operation of the Lucerne access road, this leads to deteriorating train times. The upcoming and future realizations, such as the new dual-lane introduction of the central railway in Lucerne station or the construction of the Lucerne underground station, will have an additional negative impact on stability. To secure capacity and maintain the stability of the node, an additional turnout connection and a reduction in the train follow time on the Lucerne access road are necessary.
