It's a massive program backed (in planning--don't know about funding) by Amtrak, Brandywine Realty (a developer and owner of Cira Centre), Drexel University, SEPTA, PennDOT (because I-76 and connections are involved), and I can't remember who all else. It contemplates the creation of an entirely new neighborhood over various parts of the north throat of 30th St., Penn Coach Yard, Race St. engine terminal, and Powelton Ave. coach yard, mixed residential and commercial, with lots of parkland, with some highrises near the river, their positions staggered so as not to impede a river view from farther inland. Final completion is tentatively 2040, so you may wish to clip and save this so your grandchildren can monitor its progress. One project to be tackled early is restoration (more properly a re-creation) of the underground passage between the railroad and subway stations, now separated by 30th Street. There will be a large, round subsurface plaza, apparently open to the sky, at least partially, with retail space along the route between the stations. Although beyond the scope of the project itself, there is provision for a light-rail line originating at a new plaza immediately opposite the station, west of 30th St., which could traverse the new neighborhood to be built, and possibly terminating at the Zoo, which I was told has been pushing for some time for good transportation access to 30th St. Station. (It occurs to me that 2040 is 110 years after the whole 30th St. Station idea was begun.)
There is also to be an intercity bus station just north of the station; I inquired whether Bolt and Megabus would be required to contribute something in order to use it. I was told that the City may require those lines to use the terminal rather than the Kennedy Blvd. sidewalk, and preliminary discussions indicate that those lines are receptive to paying for the use of the terminal; apparently they are already doing so at Boston South Station.
