Does anyone know why trenitalia would not list as many trains as Raileurope? I am looking up times for July 12, and trenitalia does not show any morning trains from Venice to Florence. Raileurope lists about five between 8-12. Why wouldn't trenitalia give me the most up to date info?

There may be a problem with the Trenitalia and other schedule sites not having yet loaded in Summer schedules.

Raileurope's schedule section is notoriously incomplete as a rule.

Try www.bahn.de, the German train site. It's generally good for all Western Europe.

Trenitalia currently lists nearly no trains after Je 10 when summer schedules start and if you look more closely at Raileurope sight like i did yesterday on many dates they don't list any either except some odd regional train routes. Perhaps overnight RE got more on.

This has been a recurring problem with treitalia.com for several years when summer schedules begin - they are late putting them up. Welcome to trenitalia.com!

Same thing is happening at the Bahn site

Holding off on summer / winter schedules has been typical of European trains for decades.

I find that 95%+ of the trains run the same before and after the seasonal change.
