Wissing: 49-Euro-Ticket könnte bald auch in Frankreich gelten
www.sueddeutsche.de
Er habe eine „große Sympathie“ für die Anerkennung des Tickets, sagt Verkehrsminister Volker Wissing.

Sorry for the German source, I couldn’t find an English one.

Apparently, there are first talks between the German and French traffic ministers to expand the national railway tickets (49€ ticket on the German side, a soon-to-be equivalent in France) in the respecting neighbour country. It’s still a more than early stage, will take several years and will have to overcome the incompetency of Wissing, but the idea is intriguing.
