This is all the more impressive because some years ago, to celebrate the 50th (I think?) anniversary of Interrail, the
EU» Parliament suggested the very same thing but it was rejected by the Commission as being too expensive.
Edit: It was the 40th.
In 2012 the 40th anniversary was celebrated with a free party on the Superfast ferry from Ancona to Patras with a swimming pool and DJs. An initiative by the European Parliament to offer all 18-year-olds a free InterRail pass to promote European unity was rejected by the European Commission in 2017 because of the price of 1.5 billion euros.
