I lost a navy blue baby back the 21st of September 2018. The IR 16 at 20.06, from Zurich to Bern. We stop at Brugg AG and the bag travelled to Aarau, Olten and Bern, where if nobody took it and throw it out of the train, it should be collected by the people on the train. (We called the lost and found just after the train departed from Brugg, and they told us that info)
It's reported but no luck yet. Is there a way to check that the SBB personal actually checked the train? How works exactly the process?
