I live very close to one of the stations on the Cogwheel Railway. It goes way up the steep hills, and the hills are so steep that the railway lines have a cogwheel to stop the trains sliding down. The views are awesome from it, you can see most of the city. Anytime I want to get down into the city, I use it.
I'm not sure if it's really a train, or a tram. It has the status of a tram line, but it feels like a train.
