Very good start, but as a French I fear that it may not be complete until it starts to include the high speed lines (TGV) that are the most expensive but also the most competitive when trying to divert traffic from cars or planes
To be frank, I'm amazed by this announcement. I take TER every weekend and a two-way trip is 108€, 54€ (-50%) if you get the yearly pass which costs 30€. This would save me so much money.
Yes it doesn't encompass TGV but with this 49€ ticket you can potentially get rid of many car commuters which is already a good thing :)
