I have the SBB Mobile act. And i thought we had to change trains in bellinzona (sp?) To use the treno gottardo) to lugano (not using the panoramic train) but when i put in luzern to lugano via bellinzona, it comes up with a train that says treno gottardo but it says in the direction of locarno ( which all sounds right) but it only has us changing once and that is in arth-goldau. Is that the right train? Its 2.5 hrs.
If not the right train, what exactly do we put in the boxes?
