1976 – Rescue by Union Bank of Switzerland

After several years of high operating deficits, Zürichbergbahn decided not to renew the concession. The association “Pro Polybahn” was founded in 1972 with the aim of keeping the funicular running. Though the Polybahn was due to stop operating at the end of January 1976, the Union Bank of Switzerland (SBG) acquired the railway company, rebranding it “SBG-Polybahn AG.” Decisive action was needed to meet the requirements for extending the concession for another 20 years. The railway line and both cars were refurbished in just 12 weeks.
