Hello, I have booked tickets from Geneva to Stresa with SBB on July 5th. However there now seem to be track works and my initial train, the 12.24 to Brig seems to have been cancelled. It looks like there are alternative trains at 12.07 or 12.53. Is my ticket still valid on these and if not, what options do I have. I am aware that there is a replacement bus between Domodossola and Stresa.
