We left Lucerne by train and connected to the Bernini Express for our ultimate destination Poschiavo. The Albula/Bernina railway line forms the heart of the Unesco World Cultural Heritage site. The Unesco route itself covers 122 kilometres from Thusis to Tirano. It passes 196 bridges, 55 tunnels and 20 towns along the way. It was constructed about 100 years ago. Poschiavo is Italian in nature and very close to the Italian border.
