Hi Jan,
I understand that there were no Just You'ers on board this train - thank you for your concern towards other travellers.
We've been informed by our overseas agent that the Bernina Express trains are continuing to operate however at the moment they are being diverted via Klosters round in a circle down to Samedan and then re-join the usual route.
For those travelling in September, we have been told that they are hoping to have the route back to normal by the time the group travels, however our team are closely monitoring the situation and they will contact all travellers directly should the tour not be able to operate as normal.
Warmest regards,
Julia
