Metropherique hasn't been approved yet, unfortunately. The president of the region (Jean-Paul Huchon) is against it. After strong pressures, he decided to propose multiple "Arc-Express" lines instead, lines which are less ambitious since they are neither underground nor express. Furthermore, the former version of the SDRIF doesn't plan the construction of the first line before 2025. New transports in the suburbs weren't the priority of the SDRIF. There were indeed some tramway projects, but that's all. Extension of line 11 eastbound wasn't plan before 2020, the RER E extension westbound was undecided, and line 14 wasn't extended at all. Furthermore, well, I've already mentioned how metropherique was destroyed by the same SDRIF. Anyway, Sarkozy has rejected the SDRIF, which means that it is currently re-elaborated. Sarkozy considered Huchon's first version to not be enough ambitious for the region and to lack of a general vision, something I fully agree with. Metropherique should become the first priority in public transports, as well as the extension of the RER E westbound to relieve a bit the RER A. In my humble opinion, line 14 should be extended so that it would include the Asnières-Gennevilliers branch of line 13, and get rid of the saturation of the Northern part of line 13. Furthermore, line 5 should be extended southbound to Thiais. Well, this is not really the point of this thread so I won't go further, but clearly we need something much more ambitious for public transports in the Paris area than what Huchon was planning with the SDRIF. Let's hope it will be the case in the revised version. You don't necessarily know that, but the Paris metro is one of the only in the world to serve only the center of the urban area. Generally speaking, metro networks go deep in the suburban areas. Of course, that wouldn't be possible in the case of Paris since there are too many stations close to one another and hence it would be too slow. However, there are still room to extend nearly every lines deeper in the suburbs. Jean-Paul Huchon, the current President of the region, is the antithesis of ambition in politics. Michel Giraud, his RPR predecessor, had at least launched the RER E an the line 14. Initially, the line 14 project when launched was supposed northbound to take the line 13 branch to Asnières-Gennevilliers and extending it to the Gennevilliers harbour, and southbound to take the Villejuif branch and extending it to Orly airport. Jean-Paul Huchon behaved as a butcher: He stopped all projects of extension of line 14, he abandonned the project of extension to Orly airport (replacing it by a tramway between the airport and Villejuif !! How useful !), and finally only the line 13 extension to the Gennevilliers harbour could remain because it was too advanced. But the result is catastrophic, for the simple reason that the line will be extended despite being already saturated. I hope line 14 will still be extended to encompass that branch of line 13, but unfortunately recent events don't seem to follow that direction. Anyway, if you had a good opinion of Huchon because he was supposed to do public transports in the Paris area, you couldn't be more wrong. He has destroyed all projects he could have in the hand. For instance, the extension of line 13 to the Velizy business center has been abandonned and replaced by a tramway line doing the shuttle between Velizy and Châtillon. Could you tell me the point of this ? What's the difference for people getting through Paris between taking the line 13 to the terminus and then take the bus and taking the line 13 to the terminus and then take the tram? It's the same thing. The saddest is that the Velizy business district was initially planned in the perspective of an extension of line 13. Nowadays, there's the businness district, but no heavy rail transport ! The result, huge traffic jams.
