I need to go from Interlaken to Paris, and I have been using the DB Bahn site to research options. However, I assume I will need to purchase my tickets from the Swiss SBB site so I tried to find the same routes on the SBB site. I noticed that many of the options go through Basel. On the SBB site, they sometimes require a 10 minute walk from Basel SBB to Basel SBB Gl. 30-35. However, trains from Interlaken typically arrive in SBB 7 minutes before the next departure. So, SBB doesn't allow this connection - even though it shows up on DB Bahn.
Has anyone else noticed this? Does the connection from SBB to SBB Gl 30-35 require 10 minutes or can it be done in 7? Is there a way to buy these tickets on a site other than SBB? I don't think DB Bahn will sell these tickets.
