From a cursory glance it seems to me that SNCF's debts are due to them financing all of their infrastructure instead of the French state paying for it (directly, it of course is indirectly), and then the argument goes back to the current top comment here: The real value of a good transport network is the add-on economic effects.
Also from a security perspective, you can't hijack a train and crash it into some building (it has to stay on the tracks), so that's a plus for trains.
Finally a domestic train causes about 41 g/km of CO2 emissions, while a domestic flight causes about 254 g/km (accounting for altitude) [0]
