Providing these €49 tickets requires an annual subsidy of around €3bn, on top of already substantial subsidies for the rail industry. If we accept that it reduces carbon emissions by 6.7 million tonnes per year, then that works out to €447 per tonne. That really isn't good value - most carbon abatement methods cost well under $100 per tonne.
I do recognise that modal shift towards rail may have other positive externalities, but I don't know how to price any of them.
