Yeah, I defy anyone who claims the US can't build trains "because of density" to fly to Tokyo, and actually take the Seibu Shinjuku line west from Shinjuku station. Look at those buildings built right next to the tracks, for many, many kilometers. People live in those -- if the windows opened, you could reach out and touch the laundry on the balconies that overlook the tracks [1].

Compared to that (and let's be clear: that's one average line in west Tokyo), even the Acela line in the east coast is a bad joke, density-speaking. The US doesn't build decent trains because the US is corrupt and sclerotic and run by incompetent people, not because of some mythical structural advantage in Magical Asia.

[1] I have no idea how people manage to live like that -- these trains are loud, and run basically from 4AM until 1AM every day -- but it's not lost on me that the fact that people can build houses right up next to the tracks might be the true advantage of Magical Japan.

Not that bad actually. You get used to it and even if trains are frequent they don't need 10 minutes to pass by your home.

[ButlerianJihad]

I live in a unique community which is sandwiched between a public-transit light rail line, and a freight line as well.

The light rail can run a frequency of 12-20 minutes in each direction. The freight's schedule: who really knows?

But the freight train is generally inhibited from sounding its horn or bells near residential neighborhoods. So, unless I am really paying attention while awake, I cannot detect it passing by, no matter the size.

The light rail is audible from where I sit, usually, but only just. It toots the horn mostly as it passes, but it's not disruptive or annoying to me, anyway. I sort of enjoy the white noise it all makes. There are cars that do a lot worse.

I think that the architecture here is helpful, too. The buildings are clustered around a central courtyard, and really insulated from the road noise. At any given time, there may be folks splashing in the pool, or running the jets on the hot tub, anyway.

The light rail stations are a major convenience to living here, and the train noise is absolutely the least of our worries!

[timr]

I've heard people say that, but I find it hard to believe. I think I'd go nuts. And sure, they don't take 10 minutes to pass, but the busy lines (like the Seibu line I mentioned) are running at least 2-3 trains every 10 minutes, so they might as well be continuous.

The houses built next to the crossing points, in particular, have always boggled my mind. BING BING BING BING BING....

[Liftyee]

I noticed when I visited Japan that the crossing chimes quieten once the barriers have fully lowered.

Just another example of Japanese attention to detail and human oriented design.

[timr]

Not where I am standing right now!

(I mean, maybe you’re right in some places, but it’s certainly not everywhere. Ironically, I happened to be standing next to a completely empty crossing, gates down, bonging away, while reading your comment.)

[Tor3]

The nearest crossings where I live indeed stop the chimes when the barriers have been lowered. This doesn't actually make much of a difference really, because the train arrives only a few seconds after, and, because it's a local line, there are never more than three cars in the train so it passes very quickly.

Not that I'm bothered by the chimes at all. And grandson loves them.

[fooqux]

It can be a factor of many things, can it not? Seriously, if Japan was a map option in Transport Tycoon, it would be labeled "easy".

[timr]

Of course it's many things, but people who claim that the US is especially dense, or especially sparse, or especially geographically difficult (LOL!) compared to Japan (and therefore cannot build rail) are deeply unserious commenters.

More generally, any argument of the form "the US is special for reason ____ and therefore rail is especially difficult here" is highly likely to be utter nonsense.

[barney54]

The U.S. can build trains and has a good rail system—for freight not passengers. It’s not obvious how Japan moves freight, but the U.S.’s rail system evolved to move freight efficiently. That is a huge difference and not necessarily the result of corruption or incompetence.

[timr]

Maybe. Japan has plenty of freight by rail, but you can’t look at (say) the California high-speed rail debacle and blame that on cargo.

[jabl]

My understanding the rail share of freight is relatively low in Japan compared to many other developed countries. Most freight moves by truck or coastal shipping. Looking at a map of Japan, most of the cities are by the coast, so I guess coastal shipping makes a lot of sense.

I think a big part of it is also that (partly because of the necessity of building for earthquake resistance), Japanese construction is a lot more robust than American housing, and also tends to have extremely good soundproofing on windows and doors. Actually, it's most of the rest of the world, except the US.

[tdeck]

> Japanese construction is a lot more robust than American housing, and also tends to have extremely good soundproofing on windows and doors.

This must be a different Japan than the one I'm familiar with, where exterior walls are often uninsulated and only a few inches thick and single-pane windows are still the norm in a lot of housing. I wouldn't be surprised if soundproofing were better for railroad-adjacent buildings, but compared to American homes the soundproofing here is surprisingly poor.

[timr]

> Japanese construction is a lot more robust than American housing, and also tends to have extremely good soundproofing on windows and doors.

Oh, you’re definitely engaging in Magical Japan, here.

While building standards have certainly improved in the past 20 years, the average Japanese house is built just strong enough not to fall over when someone farts. In particular, windows tend to be single pane, and you’re lucky if they block a strong wind, let alone noise.

I’m exaggerating a little, but not by much.

[Tor3]

As the sister comment said - the houses are just strong enough not to fall over in a "normal", all-the-time earthquake. Our house sways a lot under typhoons and far-away earthquakes (far away = long wavelengths). It's only relatively recent that building codes have been updated to handle real earthquakes without falling over like a house of cards. Remember the Noto earthquake Januar 1, 2024? Large areas didn't have a single house still standing.

(Which is why we're now tearing down our old house and building a new, stronger one. Post-war Japan was more concerned with a) building a lot of houses, and b) keep lots of jobs, which meant, as far as houses were concerned, building use-and-throw-away houses. Then build another. And another. And don't talk to me about sound proofing.. it's non-existing. What with no insulation in walls.)

[aposm]

When I lived in Japan it was in a relatively recent (last 10 years) but not brand new apartment block - Maybe if you are talking about a rural area or an old postwar Showa era house, sure. But either way the sound proofing is worlds better than any new construction in the US.

[Tor3]

I'm in a 20 year old two-storey apartment right now (while we're building a new house), and the sound-proofing isn't non-existing but not as bad as some other apartments I'm aware of (where you can't make a sound without the neighbors start knocking on the walls/floors, and you're privy to thing you don't actually want to hear..) - but we can hear every footstep when the neighbors walk the stairs to their upper floor. The rooms which are more distant are fine, we don't actually hear them talking. Most of the time.
