In October 2006 my wife and I were invited by some good friends in Switzerland. We had some interesting train trips, over four days. Here are some of our impressions from the trips.
Day 1
Winterthur to Guarda
Day 2
Guarda - Scuol-Tarasp - Guarda
Day 3
Guarda - Samedan - Poschiavo - Pontresina - Guarda, with the Bernina Express
Day 4
Return from Guarda to Winterthur
This was a wonderful trip. It is highly recommended to visit Switzerland and their fantastic railway network.
