-This train departs from Gare Sud in Nice, not the main train station.
-There are only four departures from Nice: 6:43, 9:00, 12:45, 17:00. Another at 18:17 makes half the trip.
-There are two passenger cars. Seats are well padded but do not recline. There are big windows for viewing. Long, narrow windows at the top can be opened a little. This is an old train and old train track. The train bumps and weaves along. It is not the TGV. It is not the most comfortable ride. Don't use the lavatory at stops!
-There did not appear to be air conditioning in the passenger cars. It could get pretty warm (hot) in there in warm weather.
We went to Entrevaux (half way to Digne), a one and a half hour trip.
-The first half hour to forty five minutes you see some housing and industrial areas, then you get into mountains and gorges.
-Entrevaux is the ninth stop. The first seven stops would be of no interest to tourists. The next stop, Puget-Theniers, might.
-Entrevaux is especially interesting as a living medieval village, unaltered for tourists. It has it all... bridge over the river with a portion that could be lifted for protection, impressive gates to the city, a warren of buildings, a wall that zigzags up the mountain to a fortification above. There are a couple restaurants. It's great for picture taking.
Perhaps there are other interesting villages farther along the route.
