In order to expand and improve the public transport offer in the Lucerne agglomeration, the project "Double-track expansion and undergrounding of the Zentralbahn" was realized in the period 2006-2012. The tracks of the Zentralbahn between Lucerne station and the Kriens-Mattenhof stop were laid in two new double-track tunnels over a total length of approx. 1,400 meters. Approximately in the middle of the two new tunnels "Hubelmatt" and "Allmend", the new underground stop "Allmend" was built, which serves, among others, the Lucerne Exhibition Center and the sports facilities on the Lucerne Allmend.

Services
