> I'm wondering why there's such a large difference in certain areas between weekday rush hour and late night though (for instance, clicking on 68th St Hunter College and changing between weekday rush hour and weekday late night is making 59th street go from 2 mins away to 12 mins away). Fewer 6 trains, I'm guessing - they come roughly every 3 minutes during rush hour (and the trains are still crowded) but that wait time goes way up late at night (that delay goes all the way uptown on local stops past 59th st). What I'm not certain about is why the delay isn't nearly as different between local stops below 59th st.
