Hello jmlsalas
The chat is not available 24/7, for example not during the night; you have to consider the time difference between the U.S. and Switzerland.
The phone number from the U.S.: 011 41 51 225 78 56 (24/7; waiting times are possible).
In the SBB Community we can also help with route and ticket questions, and this free of charge, in a speedy manner, and in English language. That’s the purpose of this plattform, not to bothet the SBB Customer Service.
Best wishes,
Roland
