Lake Lucerne? Yes, there is a lovely railway there, the Rigibahn. It goes up the mountain from two stations, and has one top station. There are lots of boats crossing the lake, and the Pilatus is not far away.yu If you planned it properly, you could also do the Furka Oberalp railway, also known as the
Matterhorn Gotthard Bahn.
Lucerne railway station is one of my (many) favourites.
I stayed at a Hotel about ten minutes walk from the centre of Lucerne. Then I went to Locarno for a few days.
I would also libe to return to Iceland, and see the waterfalls at a more leisurely pace.
