Hi DC1961
The Day Saver passes are valid at most trains in Switzerland, it does not matter which route you wanne make.
If you have booked a super save ticket with the route printed on it, then you have to contact the SBB Contact Center for help: Tel. +41 848 44 66 88 (CHF 0.08/min.) (available 24/7, sometimes you may be required to wait)
