I am taking the Golden Pass train from Montreux to Interlaken Ost then catch train to Lauterbrunnen and Wengen. Schedule shows a 6 min transfer at Zweisimmen. Not sure if it would be worth putting baggage in locker and exploring area around station, it will be around 11:30 so maybe grabbing some lunch and then catch next train to Interlaken?
Thanks,
Steve
