I am travelling to Swiss soon and booked a Saver day pass (2nd Class, Full fare for CHF 52.00). I want to travel to Zurich to Lauterbrunnen & return, Lauterbrunen to Murren & return, Lauterbrunnen to Wengen & return (cable car) - all on the same day. Does this Saver day pass cover the above train lines and cable cars? OR do I have to buy separate tickets for the different train lines? I’m a bit confused with all the info. Please let me know if I need to buy separate train tickets using the Saver day pass. Thank you in advance!
