Um, it's strange that you're starting this post a day after this project was put on hold.

Also, the story you posted (without a link) is about the new NJ Transit expansion of Penn Station under 34th Street, not Moynihan Station as stated in the title, which is the redevelopment of the Farley Post Office into a new entrance to the existing platforms at Penn Station. And the renderings you posted are old renderings of the Moynihan project and of an idea for the redevelopment of the main part of Penn Station if Madison Square Garden had been moved to 9th Avenue (and which is not happening now in light of MSG's refusal to move and currently under-construction renovations of the existing MSG).
