My Tip: travel to Berne and see the "Senkeltram" - it's a tramway that is part of the public transport system but it travels vertically. That's the literal translation: 'Senkel' - short for 'senkrecht' - vertical and 'Tram' for 'Straßenbahn' - which means tram. Duh! It is not entirely clear what differentiates it from an ordinary lift, except that you have to carry a valid 'billet' (tram ticket).
