New help to plan Chateau de Chillon and Jungfraujo

Hello terryY! I think you'd manage to visit the Chillon Castle and catch the 1.45 pm Golden Pass train on day 2, but it would be a tight schedule. There are later connections too, such as the 15.45 pm train (the only difference is that the last part of the route from Zweisimmen to Interlaken will be in a regular train, instead of a Golden Pass train). Luggage lockers are available at the Montreux railway station.

If weather is nice, I would definitely advice to make the Jungfraujoch trip, considering trips to Bern and/or Lausanne as back up plans for bad weather. The Jungfraujoch and Pilatus are quite different. If time and budget allow, you could even try to visit both. Lucerne has lots of other trips to offer too though.

You may want to take a look at the several rail passes. A Swiss Saver Flexi Pass or a Swiss Half Fare Card will save you lots of money. The timetable may come in handy as well.

Does that get you started? Best regards,
