Hi there,
I am looking at a day trip from Würzburg to Rothenburg ob der Tauber on the 18/10/2025. From the DB website, I will need to take RE10, RB81, RB82 with a total journey time of 2h 10m.

But yet if I go back to the 9/10/2025 and earlier, there is the RE80 available which will shorten the trip by an hour.

Is the RE80 on some sort of seasonal schedule?
Thanks
Jackson
