Thank you for your kind reply, but I believe what you referenced is not the one, I need to take Train des Pignes from Nice Gare du Sud to Digne-les-Bains, not the train to Annot or elsewhere. The ending stop I am looking for is Digne-les-Bains.

"This 1-meter gauge railway runs between Nice and Digne-les-Bains, 151 km, and takes about three hours. The track follows rushing rivers and steep-sided mountain valleys, many not accessible by car, and the view is magnificent. The ride is an adventure. The stations are old, tiny and personal, with everything on a human level. The name Train des Pignes comes from the pinecones, once used for tinder to start the steam engines."
I'm trying to figure out what time to be at Gare du Sud to catch a 6:55 am train that will not issue advance reservations. I think I will just stop in at Gare du Sud upon my arrival in Nice.
Merci!
