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.

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.

  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 2y 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.
    - jonahrd 2y 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 2y 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.
    - macNchz 2y 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 2y 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 2y 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 2y 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.

    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. https://en.wikipedia.org/wiki/Henry_George_theorem?wprov=sfti1# https://en.wikipedia.org/wiki/Henry_George_theorem?wprov=sft...

      - lotsofpulp 2y 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.
    - icegreentea2 2y 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.

  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 2y 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 2y ago
      People do have to walk from their cars too (for any city I've been to)
- bobthepanda 2y 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 2y 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.

      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.

  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.

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. https://en.wikipedia.org/wiki/Wuppertal_Schwebebahn https://en.wikipedia.org/wiki/Wuppertal_Schwebebahn https://en.wikipedia.org/wiki/Las_Vegas_Monorail https://en.wikipedia.org/wiki/Las_Vegas_Monorail https://en.wikipedia.org/wiki/Mexico_City_Metrob%C3%BAs https://en.wikipedia.org/wiki/Mexico_City_Metrob%C3%BAs What others have I missed?

  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.

  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.
  - School-Cotton 2y 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-Template-map-2023.pdf https://www.suntran.com/wp-content/uploads/2021/06/Sun-Link-... .

Your claim that any 500k city could benefit from a subway is wildly over-general. It entirely depends on the type of city.
    - Tade0 2y 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.

With subway lines costing a billion dollars a mile that just makes no sense.

  Where did you find that cost? eDIT Looks like you are right for the US. In other countries it's apparently much cheaper. https://www.hsrail.org/blog/why-transit-projects-cost-more-in-the-u-s-than-almost-anywhere-else-and-what-we-can-do-about-it/ https://www.hsrail.org/blog/why-transit-projects-cost-more-i... > For example, the Purple Line in Los Angeles cost $800 million per mile. By international standards, the New York price tag is stratospheric: A project in Madrid cost $320 million per mile, and one in Paris cost just $160 million per mile.

> 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 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.
asah 2y ago
Hard no: subway infrastructure is incredibly expensive and only makes sense for high density cities. Moreover, with self driving electric cars, cities will see many of the benefits at far lower cost.

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.

With subway lines costing a billion dollars a mile that just makes no sense.

Where did you find that cost? eDIT Looks like you are right for the US. In other countries it's apparently much cheaper. https://www.hsrail.org/blog/why-transit-projects-cost-more-in-the-u-s-than-almost-anywhere-else-and-what-we-can-do-about-it/ https://www.hsrail.org/blog/why-transit-projects-cost-more-i... > For example, the Purple Line in Los Angeles cost $800 million per mile. By international standards, the New York price tag is stratospheric: A project in Madrid cost $320 million per mile, and one in Paris cost just $160 million per mile.

most us cities did have subways (or streetcars), then GM bought 'em all and shut them down. [0] [0] Taken for a Ride - The U.S. History of the Assault on Public Transport in the Last Century: https://www.youtube.com/watch?v=p-I8GDklsN4&t=1590s https://www.youtube.com/watch?v=p-I8GDklsN4&t=1590s

Did the US have any subways shut down? I know there are some metros like Cincinnati that abandoned an unfinished subway

> 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 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.

Hard no: subway infrastructure is incredibly expensive and only makes sense for high density cities. Moreover, with self driving electric cars, cities will see many of the benefits at far lower cost.
