Hello readysetrobbins
Welcome to the SBB Community. A hello is always making us feel happy.
First of all, you should never ever post your tickets in a publicly available forum that can be accessed by the entire world. Your ticket snd your personal data can be subject to crime. We do delete it.
This ticket is valid for the Bernina Express; there is no via since you selected the direct train from Chur going to Tirano and it uses the most direct way.
You can always change via and pay for it at the station, or on board of PE / IR trains provided the departure and arrival station remain the same.
Kind regards,
Roland
