Personally I think it sucks.
It's better then most subway systems in new york city, but don't compare to those outside of the US like in london, china even the dominican republic is doing better so far.
The trains are filthy, i advise you take hand sanitizers or babywipes with you when you ride so you can clean your hands the once your out.
The trains get delayed for the silliest reasons.
Slightly bad weather causes you to be late. a little rain and the
M train slows down and the L takes a bit longer.
I actually think the L is pretty nice, the new trains look cleaner, brighter and more comfortable.
Almost all train stations have homeless people sitting on the chairs or beging for money. Those guys that say they need money "not to do drugs but to stay off the street" yea right, go to school if you want to stay of the streets, get a job, stop buying 400 nikes and get some converse and save your cash.
The conductors are really rude and sometimes they dont even know where the train stops, and they should know that.
59th street is so packed in the morning that it can actually be dangerous. 49 St and Fulton St suffer the same fate.
I'm not saying it's the worse thing ever, I'm fortunate to have this system, or else I'd likely have to walk everyday from BK to manhattan.
cars are to expensive and there barely any parking availabled ever. unless your willing to pay alot f money for your own parking spot.
