Yes? That's about 100 years old and not part of the NYC subway. It also requires you to leave and pay again on the NYC Subway. It's a great system, and about a 12 minute walk from my apartment, but not what I meant. Not sure where you're going with this?

Anyway, I was thinking more along the lines of extending the 7 to NJ.

Enter the train at Secaucus, for example, then be able to go to Grand Central Station. Part of the hassle of mass transit is that if you need to make 3 transfers, and have to wait 10 minutes at each one, your commute gets long fast. Extending the NYC Subway in NJ would have several benefits, including reducing the slow crawl through the Lincoln tunnel, where almost 7000 busses cram in daily.
