If you subscribe to emails from the SNCF, you will just have received an email notifying you that train tickets for September will go on sale May 4. You heard it here second !
I heard it here first! Thank you for the heads up, Kim.
But it's now June, and the train I want - CDG to Blois, departing 11:19 is not listed on the Sept date I want. Does that mean it won't be running any more?
Some tickets for July were released last week. You have to be careful ascribing an "all" denominator to SNCF emails
