European guy who used to live in NYC here.
The NYC public transit system has a lot going for it - and some real deficiences. On the plus side is:
- Extensiveness: It actually covers most of the city and with the commuter lines much of the region too.
- Speed: It is fast also by international standards. Distances in NYC are large and the subway is designed to cover it from the beginning, several lines with express trains, while may other cities have had relatively slow lines extended to the point where the commutes become unbearably long. Paris for one fell into that trap, and had to build a second, faster system, but still has pretty lousy coverage of the sububs, which they are working to amend though.
- Ridership: It has far the largest market share of commutes in the US and it is also high by international standards. But this is just as much due to the sheer size of NYC and the bridge and tunnel dependent geography. It would take a really lousy transit service to get anyone in their right mind takes a car into Manhattan unless they really need to.
- Around the clock service. Yes this is an asset. Just the convenience of not having to find your way around an alternative system in the middle of the night is great. And a bus from Midtown to say Jamaica how long would that be, even with night traffic - an hour and a half? Effectively that sort of night transport would stop connecting the city.
But there are serious deficiencies too, due to the decades of neglect, they are now trying to catch up with as well as to the basic layout of the system:
- Capacity. More riders than it was ever designed for. This feature it shares with a lot of other older systems, London being the prime example.
- Interchangeability and cross town connectiions. Many of the lines were as far as I understand it built by several private companies, and thus never planned as a network. Most of them run along Manhattan, because that is the logic of a single or a few lines, but getting from somewhere on the East side to somewhere on the West side will sometimes require going to Brooklyn for transfors or having several of them. As for system layout London easily takes the prize - more than one conveniently located transfer is rarely needed. (the new transfer center in lower Manhattan will alleviate this, but only to some extent)
- outer borough connections: an even graver example of the same. The one cross town line there is (the G) has no transfer stations with half the lines it crosses.
- lousy air port connections. No connection to LGA and two seat connections to both JFK and Newark. Why on earth they didn't take one of the existing lines and connect it into JFK (and another to LGA) is beyond me instead of the inconvenient and overpriced Air Train (though much better than before). I know there is some stupid thing about the federal funding for airport connections that can not be used for general transit, but really? Here you would have to look to Europe or Asia to see how it should be done, and in all immodesty I think my native Copenhagen takes the prize with both a commuter rail (every 10 min) and the metro (every 4 min) connecting to different parts of downtown in less than 15 mins, and leaving from right under the terminal floor.
- Commuter lines dumping everybody in the same point. The ESA will solve this for LIRR, which also has good connections at Jamaica. But the massive terminuses for NJT at Penn and Metro North at Grand Central are inflexible and impractical and creates crowding on the rest of the system.
- Appeal. Yes it is sort of murky and worn, often looking dirty even when it really isn't.
As for the ranking I have ridden too few. I like Portland for the airport connection and it seems to be the right kind of system for the size of the city, but haven't used it extensively. Chicago has a quite extensive network but seems to have connectivity issues too (no metro connetion to Union Station?) and a maintenence backlog. DC is fairly good and seems to be the one where state and county borders has not stopped the development of a sensible network, but is also running into capacity problems.
