I am in Paris now and have already taken an SNCF train for our wonderful trip to Mont St Michel (lucky that the train was running during the strike!). It was an actual ticket provided by the ticket office so the validation process was easy. So far, it looks like our next train to Brive la Gaillard for our voyage to the Dordogne valley is also running and our trip is this Friday. But, I received an electronic train ticket and printed it at home, so I wonder if and how I can validate it in the machine at the station, or if I need to go to the ticket area and get a "real" ticket? It seems like maybe I can cut it into the correct the size and try to put into the validation machine at the station, but I'm not sure if that will work. Does anyone have experience with this that could help me? Many thanks!
