I thought I remembered that the Italian train schedule was revised on June 12. I mistakenly thought that meant all the trains would show up on the Trenitalia website then. Regional trains are there, but not the high speed one I was interested in for the end of September. ( Firenze to Milano)
Where am I going wrong? The ones just one week before have been listed since April.
Thanks in advance for your help and understanding of my crazy American way of planning far ahead.
