Every great railway station needs a guardian angel. Zurich has one of the quirkiest. A colourful sculpture of a curvaceous, swimsuit-clad woman with golden wings hovers over the main concourse at the city’s Hauptbahnhof. L’ange protecteur by French artist Niki de Saint Phalle is as intriguing as the busy departure boards. With direct trains to destinations across 10 countries, this station is rich in possibilities. Anywhere from Amsterdam to Zagreb! Berlin, Bratislava or Bologna? Or perhaps Paris or Prague?
