    In Paris, yes. In Lille, no.

      Ok, but Paris transports way more people that Lille ever will. And if you want to add Lyon, well it's like paris and it's the second/third city in France.

  Thanks, it seems it is also the case in Vienna. Maybe it happens in other European countries, but in the cases I remember you need a ticket to enter: Paris, London, Madrid, Barcelona, Lisbon.
