This doesn't have anything to do with music, but I have to say that the most wonderful train ride I've ever had was riding the DART (rapid transit in Dublin) from end to end. The north end is in Howth, which has beautiful headlands for a short hike to a lighthouse and a view of Dublin Bay. The route south of Dublin has a beautiful view of the Irish Sea, and is best taken at sundown (maybe sunrise, but I never get up that early).
