It seems it is sometimes not possible to get a direct route without changing trains, and sometimes connections times have about 6 minute windows.

Should be I worried about this?

Sorry if this is a really stupid question. We've never travelled on trains in Italy before...

thanks,

we only took a train from Nice to San Remo and found the time to get on and off surprisingly short - you really have to be ready at the door.( unless of course it is the last stop).

It is not at all a stupid question!

When I took the train from Rome to Venice and back, the stops were very short. We had to be ready to move.

You should be able to tell from bahn.de whether you have to change platforms - with only six minutes you would hope you just have to cross from 2 to 3, say. However, in my experience Italian trains do NOT run to time. I once booked a 10 minute connection in Milan through a TA and she thought I was nuts. I wouldn't have made it if the outbound train hadn't been on the next platform, and if I hadn't walked through the inbound train to the front. I think six minutes in Italy is optimistic.

sounds difficult, as i suspected.
thanks for your input.
