Oh, no. There’s no room for one more track at the Central Terminal!
It’s a good thing we have all those braniacs working at the New York State Department of Transportation to tell us things like “the presence of freight traffic would make the Central Terminal ill-suited to be a passenger rail station again.” They must have done a lot of work coming to that conclusion. I mean look at this picture:
There’s no room… like… ANYWHERE from that view to put one more track. The Terminal was only able to handle 80 passenger trains a day in it’s heyday with 14 platforms and… oh… underground access from the [now disconnected] passenger platforms to the main building.
Nope, don’t see how that could possibly work.
Update: Here are two photos that show the amount of track that used to be around Central Terminal.
