Paris has "grand correspondences" which means the lines link on the map, but in reality are a long way apart. There are many travelators (think flat escalator), and even had a "high speed" one, which was fun, but I think now ordinary speed, injuries maybe. In Japan there are snow avoidance passages with shops in Sapporo and it seems an ever expanding underground links for the stations near to Tokyo station. Longest at the moment seems exit C2b of Otemachi station to the very South exit of Higashi Ginza station, 35 minutes, 2.7km.

High speed moving walkways are usually prone to falling, but also are usually bespoke machines with all the maintenance nightmare that entails. It‘s hard to upkeep lots of normal escalators let alone a specialized one.

  Travellators are surely fairly standard - most major airports have dozens. And the Paris metro has enough that I imagine they would reuse one or a handful of common designs across their network.

    Normal travelators are very standard. They‘re very slow, though, operating at ~2 km/h What the grandparent is talking about was a high speed travelator that accelerates people to 9km/h to provide shorter journey times. http://news.bbc.co.uk/2/hi/europe/3001182.stm http://news.bbc.co.uk/2/hi/europe/3001182.stm

      Toronto airport also has (or at least had, it's about 5 years since I was last there) travelators which start slower to allow you to get on/off and then accelerate in the middle (they work by the individual segments getting "longer" and "shorter"). Not sure how fast they go but it definitely feels quite a bit faster than normal ones.

        Yes, and they're infamous for breaking all the time.

        Isaac Asimov's Caves of Steel predicted banks of travelators running in parallel, where the one at the edge would go at a walking place and each successive one would go faster so you could travel many miles at 30mph or more.

>Paris has "grand correspondences" which means the lines link on the map, but in reality are a long way apart So they're not marked with a different color or something? It just looks like two dots are equally distant, but one set is farther apart than the other? Also is there a french word for "grand correspondences"? I have an interest in urban planning, but I don't speak anything other than English fluently but I'm getting good at reading small bits of text like news articles or signs and translating what I won't know with software, but it's a slow and laborious process -- sorry for the barrage of questions :-)

  It seems that a possible French term is "grandes correspondances", but "grandes" means "big" or "great" and some uses of this term seem to refer to important connections or major locations for connections, as opposed to physically distant ones. (Like if we referred to "the biggest tourist destinations", a common interpretation could be the ones that receive the most tourists, rather than the destinations that are themselves largest or most populous.) "Correspondances" are what could be called "connections", "(inter)changes", or "transfers" in English (either locations for, acts of, or opportunities for switching from one transportation service to another). The word is also used for situations like air travel connections, not just subway connections. I only speak a little French and mainly formed these conclusions from some brief web searching just now. :-) This Tweet refers to "la plus grande correspondance souterraine possible sans prendre un seul train" (the largest [i.e., longest] possible underground connection without catching a single train). So, it can clearly refer to a physically "large" distance to travel for a connection. https://twitter.com/ElyssFr/status/1031511189325373440 https://twitter.com/ElyssFr/status/1031511189325373440

> … near to Tokyo station. Longest at the moment … 2.7km. I walked that route once, about twenty-five years ago. We had had an unusually heavy snow for Tokyo and I needed some exercise, so I took the subway to Otemachi and walked underground to Higashi Ginza and back. The areas around Shinjuku and Osaka stations also offer vast, mazelike underground pedestrian networks. I used to pride myself on knowing the entire Shinjuku system, but it has expanded since and now I might get lost. After many trips to Osaka, I feel I know all the nooks and crannies of the network there, but it has probably expanded in the past couple of years, too.

The underground transfer from Yamanote to Keio Line in Tokyo Station (how you get to Disneyland/Chiba/Makuhari Messe) is so long that it's actually faster to go to the next Yamanote station, go outside, and walk back to it.
