>>1968534basically tokyo's systems were planned better since only one line was prewar and the systems can't be directly compared because of how they are used. pretty much all of the nyc lines were pre war. there's been the chrystie st connection, 63rd st tunnel, sas, hudson yards extension, eastern queens stuff, and probably a couple other things I'm forgetting, but most of the trackage and tunnels were built and designed long long ago, and for shorter trains. idk why stop spacing is so tight on the local trains, but that adds a bunch of unnecessary stops. The side by side redundant lines that the IND created also add a bunch of stops but I would call necessary due to the next point: Nyc has a denser core. Even the entirety of Manhattan is more dense than just the densest tokyo ward. Brooklyn is pretty comparable to the 23 wards in density. tokyo has a larger suburban population than nyc, shitton of people commute to 23 wards from rest of tokyo prefecture, chiba, kanagawa, saitama, etc on the commuter lines and with the yamanote they can pretty much get to all the major business districts without using a subway line. nobody rides tokyo metro/toei subway (expensive fares!). Opposite in new york, very few 5 borough ppl ride LIRR/MNR compared to the subway. so nyc has tighter stop spacing and only comparing city limits isn't showing the full picture vs entire metro area because nyc is more city proper focused whereas the tokyo metro area is more continuous and there is less of a distinction between commuter rail and metro (and some of the commuter lines run into the subway tunnels anyway)
