We are planning to take a train from La Spezia to Lucerne on June 15. On RailEurope I found the following schedule: La Spezia to Milan (648); Milan to Arth-Goldau (14); Arth-Goldau to Lucerne (2174). I don't want to purchase on RailEurope, so I went to Trenetlia's site to check schedules and pricing. When I enter Le Spezia to Milan, it says "No Solutions Found". I find this confusing and hard to believe given all the trains from Milan to La Spezia each day. What am I doing wrong? Thanks for any help.
