Hi Stephcihon -
Welcome to My Swiss Alps. That's a nice ride around the lake and along the Rhone Valley.
There is no Swiss Rail Pass. You are probably referring to the Swiss Travel Pass, which provides the coverage you describe. It works on all public trains, buses, boats, some cableways, and offers discounts on some excursion or mountain lines.
Details are here, including a map of coverage:
Lots of other information also on the page and the links there.
