Zürich’s new tram line to the Affoltern district is facing significant delays and challenges, including around 100 public complaints and potential cost overruns. Originally set for construction in 2026 with an expected completion by 2030, the project could see costs rise by millions due to inflation and land price increases. City Councilor Michael Baumer warns that delays are not an option as discussions with the Canton of Zurich continue to find solutions to stay on schedule.
