The plane industry is heavily subsidized and manages to get (IMO absurdly) low prices for some rides, and there are some situations where it's more convenient to take a plane than the train (for instance if you arrive from a long distance plane trip and are already at the airport). French trains, especially the high speed ones, are very comfortable and "high efficiency". They can be pretty expensive however.
