なぜ日本の鉄道は「異次元」の正確さを誇るのか？世界が驚嘆するインフラの秘密

日本の鉄道網は、なぜこれほどまでに高精度で、かつ快適なのでしょうか？定時運行の徹底から駅の効率的なレイアウトまで、日本の鉄道システムの背後にあるエンジニアリングや運営の哲学について議論しましょう。

the railways are excellent, but it's funny. I was just in Kyoto and saw flyers seemingly at every single temple opposing the Hokuriku Shinkansen extension. apparently this type of opposition has always existed (I looked at the history of trains in Japan and originally most Japanese did NOT want it at all because they thought it looked really ugly), like nimbys in USA, but such decisions are apparently federalized according to some Japanese nationals I spoke to, so the nimbys have no power.

USA should do the same (well, the current federal government is volatile to say, the least, but in general I think it'd be improvement).

Japan also has amazing car infrastructure too! Last time I was there visiting family in the mountains, I was quite impressed by the number and quality of tunnels and spiral ramps. The highways are similarly privatized, with tolls like train fares reducing the need for government subsidies.

It's generally regarded that Hong Kong has the best subway in the world. There are many reasons for this, but one cannot be overstated: Hong Kong's geography. A huge portion of the city consists of long thin urban corridors sandwiched between mountains and the sea. As a result, Hong Kong need concentrate its funding on only a few subway lines to support a huge portion of the population.

This good article aside, I wonder if the same thing is true about Japan when we're talking about long-distance trains. Compared to France or Germany, Japan is basically a stick. A very large chunk of the populace lies on a single train line running from Kagoshima up to Hakodate, running through Fukuoka, Hiroshima, Osaka, Kyoto, Yokohama, Tokyo, Sendai, etc. So you can slap a single bullet train line there and service all of them.

“Japan’s liberal land use regulation makes it straightforward to build new neighborhoods next to railway lines, giving commuters easy access to city centers. It also enables the densification of these centers, which means that commuters have more places they want to go.”

This is the most important paragraph in the article. It can’t be overstated how ingenious Japan’s system of zoning is and how much this has benefitted their society in ways we can only dream about here in the West.

This is a great article, but I think it’s hard to ignore that Japan’s culture of harmony is a big part of why they were able to choose sensible regulations that benefitted everyone. We struggle to pass even the most sensible land use reforms because entrenched interests want to remain entrenched even if it hurts the system overall.

Japanese public transport is good, but no match for the Swiss system. Outside of big cities, the coverage is spotty, and even reasonably large towns are only connected by reserved-only trains every couple of hours that get booked out days in advance. The almost complete lack of digitization is also remarkable (reservations have to be made with machines in the stations). There are other annoyances such as the public transport in Tokyo shutting down completely at midnight. In contrast, the Swiss government-owned system delivers usable connectivity to almost any human settlement, even most mountain villages. The ticket prices are also not so different, which is surprising considering the large difference of salaries in the two countries.

    > "I think that though we are a railway company, we consider ourselves a city-shaping company. In Europe for instance, railway companies simply connect cities through their terminals. That is a pretty normal way of operating in this industry, whereas what we do is completely different: we create cities and then, as a utility facility, we add the stations and the railways to connect them one with another."

I think this is it. The economic model incentivizes rail development. (Certainly, part of it is also cultural and legal frameworks that in the US make it very hard for this model to work)

Because the railway companies also participate in the economic activity at the destinations, they extract extended value from enabling mobility. Imagine if the rail operators owned a percentage of a stadium or convention center, for example. This then creates the economic incentive to build more connections to this "hub".

Japan is one of the only countries to have privatized parking. In Europe and North America, vast quantities of parking space is socialized: municipalities own the streets and allow people to park on them at low or zero cost. Initially with the intention of encouraging the provision of more parking spaces, Japan made it illegal to park on public roads or pavements without special permission. Before someone buys a car, they must prove that they have a reserved night-time space on private land, either owned or leased.

This is got to be a huge factor. Making everyone pay for "free parking" through inefficient use of space is such a waste. I strongly recommend everyone to read Donald Shoup's "The High Price of Free Parking".

Alright whippersnappers, let's chat about the history of railroads in the US.

In the early 20th century, US rail companies were beholding a very favorable situation: high demand to run loads of heavy freight all over the country, high demand to ferry passengers all over the country, and basically no serious competitors to either revenue source.

Now freight revenue was never going to be transformative to the industry, but it had the benefits of being reliable, un-fussy, and fairly easy to build a financial business around. Passengers, on the other hand, offered huge revenue potential, but had the downsides of being very fussy about things like safety and comfort and timeliness, along with wanting stations in convenient places and an ever-expanding rail network.

Students of US business management history should be unsurprised, then, that while evaluating the market that offered reliable revenue, versus the market that wanted large capital investments, the railroads overwhelmingly chose the freight market. In other words, US the railroad companies spoke and said we do not want passengers loudly and clearly.

The thinking was: passengers can do take the wagons and busses and cars and these newfangled airplane thingies, but freight is a guaranteed market for us! So the passengers slowly migrated to other form of transportation. But the kicker was, freight also wanted things like timeliness and access to an expanding transport network and, shockingly for the railroad execs, were willing to pay for it.

Add about 80 years, declining rail traffic, and tons of corporate mergers, and we have the sad state of US railways today: many residents have never seen a railway expansion or shiny new rail equipment, much less a real functioning passenger train. It's easy and comfortable to say that zoning or regulations or market forces allowed US rail to languish, but that would be ignoring the part where the industry did not want the customers in the first place.

This made it to the HN front page 4 days ago, under its (terrible) previous name "The secrets of the Shinkansen":
