D: Word of advice: Don't take the elevators in the NYC train station. They stink like shit and slower than a snail that it's just easier to use the stairs.

Also, keep updated on train routes because THERE WILL BE CONSTRUCTION. Seriously, I can't remember when it's never construction. The train I use daily is always in construction ever since I lived in this area for eight years now, mostly because it's the "experimental line" that they test new technology for trains. Soon we will have trains running on a computer program with a conductor overseeing it.
