The Swiss Federal Office of Transport has granted official construction approval and a building permit for a new 4.4-kilometer tram line connecting Viktoriaplatz in Bern to the Oberfeld area in Ostermundigen. The project is being implemented by the joint venture TBO AG, which includes BernMobil, the City of Bern, and the municipality of Ostermundigen. The new rail service is intended to replace a high-traffic bus route that currently serves more than 8.5 million passengers annually. Key objectives of the infrastructure project include increasing passenger capacity, improving timetable reliability, and reducing traffic congestion. The development will feature barrier-free stops to assist passengers with limited mobility and includes urban redesign elements such as improved pedestrian crossings and expanded bicycle lanes. The project follows a public vote in favor of the development by residents of Bern, Ostermundigen, and the canton of Bern. ## Timeline ### 2026-10-16: Swiss authorities approve new Bern–Ostermundigen tram line Swiss authorities have approved a 4.4 km tram line between Bern and Ostermundigen to replace a heavily used bus route and increase regional public transport capacity. 2 sources. https://clstr.news/cluster/swiss-authorities-approve-new-bernostermundigen-tram-line ### 2026-09-28: Bern–Ostermundigen tram construction receives official approval The Swiss Federal Office of Transport has approved the construction of a 4.4-kilometer tram line connecting Bern and Ostermundigen to replace a high-capacity bus route. 3 sources. https://clstr.news/cluster/bernostermundigen-tram-construction-receives-official-approval --- Cite as: Bern–Ostermundigen tram line construction approval.
