Hi,
Gordon who regularly posts on here is your best bet for that kind of info. He has a wealth of knowledge on everything Swiss railways.
Personally, I’ve seen a fair few videos on YouTube featuring the 460/465’s late 90’s early 2000’s, can’t remember if if they were hauling international stock though.
Not sure if you are a member, but might be worth joining the Swiss Railways Society. There is a great article on the 460’s in this months mag.
Best regards,
Jeremy
