I've read that our Swiss Travel Passes will get us 50% off the price of the cogwheel train from Montreux to Rochers-de-Naye. But when I go to the sbb-ch website, it shows a route using a Regio train from Montreux to Rochers-de-Naye.
So are there two different train routes? Because aren't Regio trains just regular trains that serve the regional routes? And aren't those trains included with Swiss Travel Passes?
