> The new plan has some limitations. While Germany’s 9-euro ($9) passes cover all public transit except faster train services, Spain will restrict itself to regional and suburban rail services, which are not as extensive as they are in Germany. While it might be technically possible to travel across Spain using only regional trains, it would not necessarily be easy because the slower network is quite patchy.

To be honest the German situation is not so different from the Spanish one.

Going from Munich to Berlin with the 9-euro ticket requires from 3 to 6 changes, and from 10 to 15 hours.
