What upgrades should be made to the NYC subway system?

Question:
I've never been to New York City, but I've read a little about the subway system because I like trains. From what I've read, the current system is horrendously inadequate but the only talk of upgrading is the 2nd Ave line. I welcome any comments about the size, capacity, utilization, and so on about the subway system.
