I am taking the Bernina Express from Switzerland to Tirano and Lugano Italy. I heard there is no formal immigration process when passing into Italy but sometimes we are checked by Swiss attendants on the train. I also heard we may be checked for passports leaving from Italy back to Switzerland.
I received a speeding ticket a few years ago in Italy. The cost was absurd (over 700 in USD) so I decided to not pay it. I am wondering if I pass through Italy, if I run the risk of being flagged and being forced to pay it? I imagine the fees are astronomical at this point as they threatened to keep doubling the fine if left unpaid. I would appreciate any insight. Thank you so much!
