    I'm of the opinion that every 500k+ city should have a subway line.

    I grew up in a city with one (just one for the majority of my 20 years there) and if there's one thing I miss from that place it's the ability to move at an average speed of 35km/h at any time the trains were operating, especially at 2am on a Friday night after a couple of beers with the guys.

    The other thing I noticed when I was visiting my family there during the recent holidays is that there are so few cars in places close to the subway lines - roughly half the usual concentration. The incentive to have one is just not strong enough.

    • xvedejas 11 days ago
      I'm of the opinion that it depends on density. You could build a subway line in some US cities of 1M and nobody would ride it; you could build a subway line in a city of 50k and everyone would ride it. It depends on whether there is density to support walking directly to many things (businesses, residences, and other transit lines) or not.
      • 42772827 10 days ago
        Building a subway system after the city is so dense that it will be ridden by “enough” people is exactly the wrong way to create livable urban spaces.

        Building a subway is the solution to inducing density, not responding to it.

      • balderdash 11 days ago
        Density yes, but more importantly 1) speed vs traveling by car, 2) starting and stopping in places people want to travel between, 3) safety, 4) real estate prices/regulation.

        Density goes to number 1 (more traffic = better reason to use the subway) and 2 (more likely to be able to serve people’s desired trip)

        • humanrebar 10 days ago
          5) Weather. If it's under -20 C or over 40 C, walking five blocks is unpleasant for anyone and dangerous for some. Especially if the walk is unsheltered, which it typically is.
          • xvedejas 9 days ago
            People do have to walk from their cars too (for any city I've been to)
      • HPsquared 11 days ago
        The subway is the big expensive investment. In theory, businesses and housing etc would develop around the stations. Like how suburbs develop around train stations.
        • ghaff 11 days ago
          In theory. The commuter rail I sometimes take follows an old rail right of way. Some of the stations are in fairly developed areas. But some of those, like Concord, presumably predate even the original rail. And a lot of the towns are pretty spread out. You can't walk to much until you get to the last two stops in the city proper.
          • macNchz 10 days ago
            I imagine that at least one factor there is that building up is prohibited by zoning—a super brief glance at Concord's zoning map & code it looks like the only kind of residential buildings you can build anywhere without special permission are single-family.

            Now there are surely people living there who would argue that this zoning has protected the shape and nature of the town they that they prefer, but the flip side of that coin is that, at $1.4m, a median home in Concord costs more than 3x that of the country overall.

            • ghaff 10 days ago
              There's probably some truth in that. On the other hand, Concord is a pretty far-flung suburb; you're probably over 30 minutes to get to Cambridge without heavy traffic. I believe the prison out there is closed now but don't know what the plans are for the land.
              • macNchz 10 days ago
                Sure, I wouldn't imagine it'd turn into a cluster of skyscrapers if the restrictions were not there, but I would imagine there might be some small apartment buildings near the train station. New Jersey has had some impressive housing changes happen by opening areas near transit to development in not-dissimilar environments.
                • ghaff 9 days ago
                  Apparently, the governor is interested in using it for housing development but I'm sure that will be tied up in the courts for years--especially with it being Concord.
          • jonahrd 10 days ago
            This is because the T is not a "real" transit system in the way that it's simply not designed to move enough people fast enough to compete with cars.
            • ghaff 10 days ago
              Well, if I’m going into the city 9 to 5ish I’ll usually take commuter rail because it’s less painful even if it takes as long as driving. But I do need to drive to and park at the nearby commuter rail station.
        • llamaimperative 11 days ago
          And then landowners who were “smart” enough to own land where this ends up going in get to reap all the financial upside, instead of the public which actually invested in that infrastructure.

          Just imagine if the public could capture the (financial) upside it produces, then it could apply that money to do the same thing down the road, then do the same thing again down the road further.

          • icegreentea2 11 days ago
            In some countries the transit companies (public or private) also become the landowners of the adjacent areas - this would be the "rail plus property" model.

            In fact, the rail plus property model allows the rail operate to better capture their added value, so it applies even in "private" scenarios. The most famous example would be Tokyo.

            The goal shouldn't be for the public to be able to reap direct financial benefits from the induced activity around transit hubs, the goal should be to firstly to incentivize and maintain affordable, high quality, sustainable transit, secondly to provide more and better economic opportunities.

            • shipp02 10 days ago
              This is the case in Hong Kong as well. The subway company is also involved in the malls built on top of them.

              There are malls and neighborhoods built entirely around the subway station

              • delroth 10 days ago
                Same in Switzerland, with the added quirk/bonus that shops in train stations are allowed to open on Sundays, when shops outside of train stations usually can't open due to employment laws. This wasn't originally meant as a way to increase attractiveness of businesses in train stations and other public transit places, rather as a way to make sure that people travelling have services available while on their way. But nowadays it's definitely a big reason for people to come specifically shop in train stations on the weekend.
          • showerst 11 days ago
            A version of this is common now in the US through Tax Increment Financing.

            https://www.fhwa.dot.gov/ipd/value_capture/defined/tax_incre...

            • lotsofpulp 10 days ago
              I don’t see how that is a version of what llamaimperative posts.

              If anything, TIF increases rewards for landowners who do nothing or otherwise underutilize land. Taxing the product of work to make a piece of land beneficial for society is amazingly backwards.

              The proper direction to go in is marginal land value tax rates, with increasing penalties the longer a spaces remains unused.

          • RhysU 11 days ago
            > Just imagine if the public could capture the (financial) upside it produces...

            Like through taxes on the sale of the property or the increased business income it produces? The public will.

            • Scoundreller 10 days ago
              > Like through taxes on the sale of the property

              That just encourages corporate ownership of property (unless you mitigate that), but overall I don’t know why we’d disincentivize moving closer to a new workplace or into a smaller home once it will do for you.

              • bobthepanda 10 days ago
                It also disincentivizes speculation, which is just a flurry of repeated transactions.

              This typically goes to the higher level of government. Not the local one that manage and build that transit system.
              • RhysU 9 days ago
                Why should the transit system butt into the jurisdiction of the traditional government just because transit is built somewhere?

                As a silly dystopia, imagine that a transit agency could grab revenue as you suggest it might. Then everything becomes a transit land grab.

            • llamaimperative 10 days ago
              No, taxes on the unimproved value of the land
              • RhysU 9 days ago
                Property taxes include that, generally.
      • bobthepanda 11 days ago
        Also the shape of density.

        A small city in a straight line along the coast is going to get a lot more mileage out of a single line than something spread out across a plain.

      • CalRobert 10 days ago
        In the ideal scenario you build the subway or other transit when density is low and land is relatively cheap, and THEN you make it high density.

        Doing it after the fact is much, much harder.

        • JumpCrisscross 10 days ago
          > In the ideal scenario you build the subway or other transit when density is low and land is relatively cheap, and THEN you make it high density

          Do we have examples of this working? (Genuine question.)

          • DiogenesKynikos 10 days ago
            Outside the US, there are many examples (Japan and China both do this).

            In the US, I don't know specific examples, but you can definitely use a combination of policies (building public transit, zoning laws to encourage high density, making parts of the city more pedestrian-friendly - and generally less car-friendly) to encourage high density.

          • CalRobert 10 days ago
            Definitely! Here’s a video with some discussion

            https://youtu.be/MnyeRlMsTgI?t=667&si=g-xwXEjLPPobUkzy

            There’s photos of subway stops in random fields in china that sometimes get laughs but in actuality china is just smart enough to build the subway and THEN the buildings.

            Meanwhile Japanese rail companies own land where they build rail and can make more money on the land than on the trains

        • ekianjo 10 days ago
          You don't decide to make things high density out of the blue. People have to WANT to live there.
          • CalRobert 10 days ago
            Well yes, one clear indicator of that is where homes are expensive. Like in places with great transit and amenities.
          • Too 10 days ago
            Cheap + quick commute to downtown takes care of that.

    • telesilla 10 days ago
      If not a subway at least some form of transport that won't get stuck in gridlock. Three examples I can think of are the Wuppertal suspension railway, Las Vegas monorail (though more of a tourist pull than for the locals) and the dedicated Metrobus lanes in Mexico City.

        It's only a short stretch, running the length of I-495, but the XBL in the Lincoln Tunnel is a huge reason why people bother with the bus in northern NJ.

        When I was commuting by bus, the inbound morning trip (with XBL) was 20-30 minutes, and the outbound evening trip (without XBL) was 30-45 minutes.

      • oblio 10 days ago
        They don't need silly suspension railways in most places. A tram line fits perfectly in 1 lane, so that would make it 2 lanes for both ways. US lanes are so wide that it's likely 2 tram rails fit in 1.5 road lanes, with a bit of extra room for wider sidewalks (sorely needed in most of the US), bike lanes (also sorely needed in most of the US) or just general greenery (hedges would do wonders for US urban landscapes...).

        Of course this would require that the 3-4 lane stroads give up 2 of their carlanes so instead of doing the reasonable thing, building infrastructure costing 10x is almost universally preferred.

        Heck, it doesn't even need to be a tram. BRTs are good enough for a lot of cases.

        • bombcar 10 days ago
          Well-done BRTs are probably the best thing you can get for cost/benefit. And you can subway them at points if you want, and if they get super popular you can put them on rails.
      • flyinghamster 10 days ago
        In Chicago, the "L" network also has stretches that run down expressway medians, along with the elevated lines and the subway sections downtown.
      • kjkjadksj 10 days ago
        American cities of 500k people really don’t see gridlock though. Maybe a couple blocks downtown by the highway ramps thats it.

    • keiferski 10 days ago
      Having lived in / visited a few dozen cities in Europe, I actually think trams are generally preferable to subways. In places with both, I tend to use the trams almost exclusively.

      A hop on, hop off tram system is much quicker and efficient than going into a subway station, then back up, etc. At least if you aren’t going entirely across town.

      • Tade0 10 days ago
        What makes for a more pleasant experience is not necessarily the optimal choice for commuters as subway wins over trams by close to an order of magnitude in terms of throughput.

        In the city I grew up in during rush hour subway trains leave less than every two and a half minutes and pack well over a thousand commuters each. That is an impossible feat for even the best tram system, as they're limited both in vehicle and station length, not to mention speed, as you can't have 40 tonnes of metal hurtling at 80km/h through intersections.

        • def_true_false 10 days ago
          Why can't you have trams travelling at 80km/h? That's around the max speed of some of the trams used in Europe.
          • Tade0 10 days ago
            Because at that speed its braking distance is close to 200 metres, so you need to separate such a vehicle from the rest of the traffic.

            There exist implementations of this, but it's essentially a train with extra steps.

          • bombcar 10 days ago
            Because pedestrians and drivers are idiots (or if you want to be nice, have lapses in judgement).

            Whereas it is possible to have a subway where it’s completely impossible to get on the tracks without heavy equipment or the right keys.

      • rightbyte 10 days ago
        I disagree. Trams are too slow. They are not good for long tracks, like sub ways.
        • mastazi 10 days ago
          And also they have much less capacity than mass transit systems like a subway, so they are bad for most commuters who tend to travel at rush hour[1]. I guess they are great in tourist areas though.

          [1] In my experience, at least in the cities where I have lived

          • wink 9 days ago
            Worse in the outskirts, but better in the town center if you can hop off every couple 100m without 2 escalators/staircases
            • rightbyte 8 days ago
              You could argue trams are more romantic. That is probably the major advantage.

              I'd argue there are some limited places where classical trams on the road make sense, like some down town district. But you get almost the same utility with busses, passenger flow per lane is lower with busses, for a lot less money.

      • JumpCrisscross 10 days ago
        > * trams are generally preferable to subways. In places with both, I tend to use the trams almost exclusively*

        In towns with trams I've found Ubers almost always faster. That said, most American trams are at grade, so you get a bus that can't change lanes.

      • SllX 10 days ago
        If I’m going one, maybe two stops, a tram can be optimal if it’s already in front of me[1]. Otherwise the subway tends to win the curb to curb speed contest for me. It’s a little more traversing through the subway’s infrastructure and getting to the right platform and the right part of the platform, but I’ll get to my destination in less time and it’s not even close.

        [1] Otherwise I have to check the Transit app on my phone and do some math factoring in the wait time and the time it takes me to get to the platform. The subway usually wins this contest too.

      • ekianjo 10 days ago
        Trams are super slow. They take space on the road or need their own full lanes. It's much worse than a subway.
      • euroderf 10 days ago
        Trams do need dedicated lanes.
        • keiferski 10 days ago
          Depends on the city, but in most places the lanes are wide enough that a tram-designated area isn’t really an issue. Even then, it wouldn’t be a horrible idea if an avenue (running north-south) or two in Manhattan had one less lane for cars and one more for trams.
        • markkanof 10 days ago
          Not necessarily. Unless I am misunderstanding what specifically is being referred to as a tram. In Portland, Oregon for example, we have small trains that run at street level and share lanes with automobile traffic.
          • tallowen 10 days ago
            Portland's trams don't move anywhere close to 35mph as the OP mentioned. Portland's trams are quite capacity constrained due to needing to navigate the short blocks and many intersections of downtown Portland. Dedicated travel cooridors where these trams could move at closer to 35mph would allow trips _through_ downtown to become competitive which currently are often not ideal.
            • ghaff 10 days ago

      I think ours could go up to 50 or 60km/h, but the density of stations (can’t leave any blocks behind!), station dwell times and time for one transfer puts it at equal time to cycling for me in Toronto.

      And my cycling route isn’t a more direct route (cuz our surface routes are largely a grid and we just replicated it underground instead of something more synergizing like a giant X).

      A fun hobby of mine is to open up Paris on google maps and compare the cycling and transit times in their daytime between arbitrary points and cycling often wins. Theyre drunk on station density so you’re always close to one, but it means a lot of stopping.

      Where would you put the subway line in Tucson, AZ?
      • Tade0 10 days ago
        I'm no city planner, but I would definitely connect the Amrtak station with the University of Arizona and on the other end make it reach the edge of downtown.

        The rest of the city is really spread out with all those detached houses, so I'm out of ideas but then again my city put a subway station in such a location and it serves a whopping fifteen hundred people daily - that's one subway car, but at the same time appropriately a thousand fewer cars on the road. Still worth it in my book.

        • umanwizard 10 days ago
          > I'm no city planner, but I would definitely connect the Amrtak station with the University of Arizona and on the other end make it reach the edge of downtown.

          I went to U. of A. and have absolutely never even heard of any student ever needing to go to the Amtrak station, for any reason. Not trying to be rude, but that smells like unthinkingly-applied urbanist ideology — thinking “trains are cool” and working backwards from there.

          But sure, people do go to that area for nightlife, so let’s assume you said something like “Hotel Congress” instead of “the Amtrak station”. Still, that’s less than 3km from campus — even if there were no transit options, you could bike, walk, take a rental scooter or an uber.

          But if none of those options work, fear not, there is already a streetcar that basically covers exactly your proposed route: https://www.suntran.com/wp-content/uploads/2021/06/Sun-Link-... . So why would it make sense to spend a giant sum on a subway to replicate the streetcar over this tiny area?

          > The rest of the city is really spread out with all those detached houses, so I'm out of ideas

          That’s my point. Your claim that any 500k city could benefit from a subway is wildly over-general. It entirely depends on the type of city.

          • Tade0 10 days ago
            I get where you're coming from as I have a lot of words to say to those urbanist ideologues and none of them are pleasant.

            Main reason why I think subway is superior to anything, including trains riding on the surface, is that it doesn't get in the way of anything.

            My current city is subject to a double whammy of a train and river system. The result is of course gridlock, as bridges have limited capacity and not all train crossings could be made into viaducts. Having a single subway line would greatly improve things, but alas - the city is in debt due to having built a football stadium which went way over budget.

            That being said to me American cities stretch the definition of cities. If there's no functional difference between a district within city limits and a suburb, why bother with having a distinction? I mean, we have districts of detached houses in my corner of the world, but they're former villages absorbed by cities and are gradually being densified.

            • umanwizard 10 days ago
              I get where you’re coming from, but I can’t think of a definition of “city” that would exclude Tucson. It’s a large, connected settlement of humans who don’t primarily live from the land.

              For what it’s worth, Tucson does have suburbs, which are even less dense than Tucson (e.g. Oro Valley).

            • bombcar 10 days ago
              America never had city walls, so the density pressure provided by them is only found where natural rivers and other boundaries occur.

              Subways are so expensive that we don’t see existing rail/tram lines being buried to reclaim land in some of the most valuable cities in the world.

              What's the difference between a train underground and a subway?
              • defrost 10 days ago
                In the evolution of English language usage the term "subway" is almost always associated with passenger transport by train.

                A "train underground" my or may not have passengers .. the majority tonnage of trains in mine systems is ore transport, many such systems never carry passengers although, of course, some do at shift changes.

      I wouldn't say that Maray's chart as cited by Tufte is directly comparable: it displays the timings of trains along a one-dimensional railway, therefore displaying two dimensions of continuous data for each train (the second dimension being time). The online map displays a two-dimensional area, with an extra (quantized, not continuous) dimension of time with the colour-coding. It's a tradeoff between displaying more precision for fewer train timings or less precision for many train timings.

    I love this. I agree with the "about" that it's visually compelling, and I'm mesmerized.

    This doesn't detract from my enjoyment the site, but for trip planning I'm a little skeptical of the results around the edges, especially when I'm assuming multiple transfers would be required (e.g., Local -> Express -> Express -> Local).

    With a caveat this was over 10 years ago (~2012-2013), and train frequencies may have changed:

    I used to live pretty far up on the upper west side, and took the 1 train from the 103rd street station daily. My weekday route was 1 -> 2/3 -> 7 into midtown. The 20 minute radius is accurate at peak times, when it only takes 2-3 minutes to catch a transfer. However, the website "about" makes an assumption this is for noon on a weekday. I don't think I ever made it to Brooklyn in under 40 minutes.

    Something here is not quite right. For example, if you look at the 7th ave line (red line/1,2,3) 18th street and 14th street have similar radii.

    But anyone knows that 14th street is much more convenient because it's triply serviced by the 1,2,3 with 2,3 being express trains. 18th street is serviced by one train the runs locally. This ignores that you could easily switch to the L, A/C/E, F/M with a short walk.

    Still, a cool visualization to show the power of mass transit, and even compare relatively between lines.

    • acomjean 10 days ago
      Does it include the express trains? (those trains that skip a bunch of stops on certain lines, so they can go faster like the 2)

      I couldn't figure that out. I remember when I was in NY those trains really moved.

      • wgerard 10 days ago
        I think it includes transfers and express lines. I noticed if I click on a local stop that meets an express line somewhere, the express line stops are still quite a bit darker than other stops.

        That's likely why 18th and 14th street are so similar: It only takes a minute or two to get from 18th st -> 14th st.

    • mannykannot 10 days ago
      I see what you mean. According to this map, you can get from the 18th. street station to the 1st ave. stop on the L in ten minutes, but not from 14th. street.

        I'm a huge theme park nut that lives in Orlando - I'm trying to design a version that can work across Walt Disney World (or maybe even ALL of Orlando's theme park campuses).

        Photos pose a huge challenge because my friends (fellow theme park nuts) can pick out the smallest details in every park -- even the color of pavement and themed lighting fixtures! I'm having fun thinking of what adaptations to make.

        Agreed that this product would be better as a game design framework rather than a ready-to-play game in any geo (and tbh, would be a better fit for what Jet Lag is all about: people designing games for themselves to play!)

          • ta1243 10 days ago
            Taxi companies don't like rail going to US airports. With JFK you have to take one train, then change, then another train, then you're at the equivalent of Paddington. Would be like having to change at Hayes+Harlington. Luton has this, but that's the odd one.

            From Newark I think it's a bus to a train station, then a train to NY Penn.

            The "default" way to get from Heathrow/Gatwick/Stansted to London is a train from the terminal to the centre, typically multiple options.

            The default way in the US is taxi. Massively inefficient, but a lot of people make a lot of money from it. Why have a plane load of people on a single train costing $5k, when you can have 200 taxis costing $20k, generating 4 times the GDP.

            In London, you also have the Piccadilly line depending upon where you're going and how much luggage you have (many of the London tube stations are pretty awful in terms of accessibility as I discovered on a trip where I had heavier luggage than normal last year).

              Since 2022 there's also the Elizabeth Line, which uses the same tracks as the Heathrow Express, but then continues under Central London and far to the east.

              It takes 27 rather than 15 minutes to Paddington, but it's also half the price of the Heathrow Express.

              It's the purple edged line: https://content.tfl.gov.uk/london-rail-and-tube-services-map...

              • ghaff 10 days ago
                Right. But I usually stay near Trafalgar Square and the Piccadilly line is much more convenient for that.

And, yes, Heathrow Express is something of a rip-off which the airport steers you towards.)

    Travel times would be much improved by a high speed line.

    Ie. a route with 4 stops and a travel speed of 100 mph.

    The finances of railways actually get better with faster trains - because the sooner you can get the person to their destination, the quicker you can get that train serving another passenger.

    • pavel_lishin 11 days ago
      MTA runs express trains. They don't get up to 100mph, but they skip many local stops along the way. Raising their speed to 100mph would likely not meaningfully increase transit time - you'd maybe shave off a few minutes.

        it boggles my mind that a place like new york doesn't have the money to just do that. Raising the speed limit gets more important the longer you travel and connects distant parts your city better. It's a recent trend to build high-speed lines to complement an existing, dense subway network (e.g. Paris goes up to 75 mph).

        I mean when were these built, a 100 years ago? Surely there's room for improvement.

      • Symbiote 10 days ago
        In London you can take a high speed train from St Pancras to Stratford, though it's a normal high speed train that then continues far outside the city.

        It's the blue+yellow line which goes off the east side: https://content.tfl.gov.uk/london-rail-and-tube-services-map...

        I don't think that's unusual for very large cities with high speed trains. The longest-distance trains probably only stop at one station in each city, but medium-distance trains can stop at multiple.

        I've never come across a metro train travelling that fast though. The cost of building the line to support those speeds would be tremendous for a small difference in journey time.

  • shmuppet 10 days ago
    An interesting offshoot of this type of question is: how long does it take to hit every stop on a given transit system? BART has quite a few people making attempts; the official BART website even maintains a little article [1]! A couple have made videos of attempts and theory [2, 3], but the king of these things is tomo tawa linja, who I believe is the current record holder at 5:30:26 [4].

        Which is why people prefer personal cars whenever possible. Mass transit has to operate at 5 minute intervals (so that you are waiting at most 10 to 15 minutes in the event of a missed connection).

        If it isn’t that frequent, then I am going to opt for a personal car every chance I can. Using only the subway in Manhattan/some parts of Brooklyn is convenient, but as you stray further, it starts getting tedious.

        • acjohnson55 11 days ago
          In a car, you still need to park, which in NYC might take 20 mins and still leave you blocks from your destination. The other difference is what you can do with your travel time. While driving, you're limited to passive activities. Cabs and ride share solve this, for a price.

          But people do love car travel, regardless of the problems. I have a buddy who would nearly always opt for Uber, even at times when traffic made it slower than the subway.

        • chimeracoder 11 days ago
          > Mass transit has to operate at 5 minute intervals (so that you are waiting at most 10 to 15 minutes in the event of a missed connection).

          Which is not only possible, but quite feasible. Upgrading to provide six-minute service 24/7 would only require a one-time investment of $300M, because it is projected to raise enough revenue to pay for itself in the long term.

          Unfortunately the current governor is trying to cut transit funding again with her most recent budget proposal, so that's unlikely to happen anytime soon.

          • marcinzm 11 days ago
            I'm not convinced it'd pay for itself since maintenance still needs to be done so it's not really 6 minutes 24/7. The 7 train in theory runs on weekends and in theory runs fairly often. In practice it's down every other weekend for I think 5+ years now. The MTA does not have a good track record of timely maintenance and also seems to not care much about long term downtime (ie: like their original proposal for a 15 month closure of the L line).
            • chimeracoder 11 days ago
              > The MTA does not have a good track record of timely maintenance

              A big part of that is because the MTA has been starved of funding for fifteen years now, to the point where they've had to substitute capital funds for operating funds in an effort to keep the lights on. Maintenance becomes more expensive when it's perpetually deferred - and it just became even more expensive because Hochul's inexplicable last-minute flop in June caused S&P to downgrade the MTA's credit rating, which means all future bonded capital projects will have to waste even more money on higher interest payments.

              > (ie: like their original proposal for a 15 month closure of the L line).

              That closure was intended to fix damage caused by Hurricane Sandy, and to bolster the tunnels against future climate disasters. The decision to forego the full maintenance (made unilaterally by then-Governor Cuomo as a political move) just kicked the can down the road.

                  Byford quit because of Andrew Cuomo, the then-governor, not because of bureaucracy within the MTA. This was widely reported even before his resignation was official, but was confirmed explicitly later on[0].

                  > To use a transit analogy, Byford fled the MTA because he felt like he had been tied to the tracks while a train driven by Andrew Cuomo cut his legs off, Kramer reported

                  Which is my point: the governing authorities make political decisions to starve the MTA of funding or cancel capital projects at the last minute, which harms the MTA in the long run and creates many of the problems that people end up blaming the MTA for.

          • lotsofpulp 11 days ago
            They are mutually exclusive in the US because space for cars (current US sized cars) means everything is farther apart, which means the public transit is not economical, or lots of walking. And walking is more dangerous for pedestrians due to inattentive drivers and large arterial roads with wide crossings.

            The constraints lead to completely opposite designs, which is why only very few, very dense cities in the world have convenient public transit, and they also happen to be inconvenient for personal cars.

Its most busy section was meant to be converted to metro, but due to planning permission nonsense it will just continue to be one of the world’s busiest tram lines until at least 2040 (it is actually higher peak time capacity than many metro lines at this point).

              The Victoria Line in London has a 100 second interval, although apparently in practise it's more frequent: https://www.youtube.com/watch?v=PJ0zk4MWCQY

              From a quick search, there are also lines in Paris and Moscow with similar frequency.

      The loser is 241st in the Bronx. Can't even get out of the Borough.

      Unless we're also considering Staten Island, which few do :)

        Also the Rockaways, which are famous for being remote and poorly transit-served.

    Apparently you can walk to North Brother Island in 20 minutes from 138th St.

    Does it also work at 3am?
    • jpalawaga 11 days ago
      It does. New York's system is one of only a handful in the world that operates all (or nearly all) lines 24/7.
      • acjohnson55 11 days ago
        The level of redundancy in the NYC subway is marvelous. In most of the densest areas, you have 4-track lines and often other lines within a mile. It makes it possible to do maintenance while still offering 24/7 service.

          If you have a 2-track line, you can close one of the tracks for maintenance on weekday nights when frequency doesn't need to be very high. That's how Copenhagen does it.

    I don't see any violations of locality here.

      There are a few -- select the 79th street station on the #1 line (farthest west in Manhattan) and look at Brooklyn, due pretty much directly south. The 36th Street station on the D/N/R lines is reachable in 40 minutes because it gets express service, but the stations to the north and south are local stops, and for that reason, take longer to get to.

    Yeah. Isochrones are great, because they clearly show the inferiority of ANY type of public transit to cars.

      FYI, the average speed of a car in midtown Manhattan is under 5mph. The subway is 17mph.

        does it include going to subway station ("total time of travel")

      Is the migrant crime the only crime you are trying to get away from? Are you ok with local crime? One would hope you just want to escape crime, unless you are insinuating that all crime is migrant crime or most crime is migrant crime. Neither of which is true.
