UPDATE! FINISHED! June 2017, only 5 years late. The new station has been inaugurated. That does not mean that it now takes passengers. It's a photo op for politicos to stand around and pat themselves on the back. "All aboard" starts next month. At least, that's what they say, and they wouldn't just make that stuff up, right?
One of the most successful such efforts in Europe has been the Ruhr region in North Rhine-Westphalia in east-central Germany. It is one of the most densely populated areas in Europe and was one of the most heavily industrialized. Over the last few decades, "post-industrialization" has taken place, and the Ruhr now has theaters, cultural centers, festivals and museums (including what are now called "industrial museums"). As a run-up to the Culture Forum, a gentleman from the Ruhr, Hans-Dietrich Schmidt, was in Naples the other day to explain the "Ruhr model" to local officials and business persons who would like to use that model for the further development of Bagnoli, once site of the Italsider steel works. Bagnoli has had some successes: a new theater, the North Pier, a hands-on science museum and exposition ground called Science City, a "Turtle Point" extension of the Dohrn Aquarium, a Maritime Museum, etc. There have been failures as well, such as the failure to lure the America's Cup regatta to Bagnoli a few years ago, which would have meant money for the construction of a suitable harbor. Some things are still up in the air, such as a proposed Bagnoli Green Park and an industrial museum. I gather from various sources that Herr Schmidt's presentation was a pretty solid pep-talk. You need two things: money and political will. One of those items alone won't do the trick. Both might. [This item is also included on the Consolidated Bagnoli page.]
