Never been to London, got 6/9. Presumably anyone who did this and got a poor score isn't posting, so only people like me who got good scores by chance are represented.

Got 3/9 and live in London. Really only a single one of which I both had confidence in and got right.

Most people on the tube have headphones in anyway tbh.

Pretty cool —- should do it for NYC subways!

Doesn't NYC mostly (mostly) use the same trains across the network? on the tube, each line was (historically) operated by a different train company, so most lines have a (somewhat) different profile but dedicated rolling stock to each line, along with different aged stock dependent on the procurement cycle or even age of the line itself. Boston T would be a better one as each of the colour lines are significantly dif…

Not that many different stocks now. The 4 sub-surface lines were given S7 or S8 stock according to platform length, and while it's entirely possible an S7 does sound different from an S8 I wouldn't count on it because these are basically the same train.

So that's a change from 5 stocks (two A variants, two C variants and a D) across four lines to two (S7 and S8) in terms of the rolling stock. The deep tube lines will all get variations on the 2024 stock, likely in 2027 although I believe the announced date still clings to "late 2026" but for now are all distinct.

The NYC subway (and elevated) trains were also originally operated by several different private companies, and there are still at least two major types of rolling stock (used separately on "A" division and "B" division lines). Maybe less variation than London, but I really couldn't say having never been to London.

Chicago's "El" and subway system AFAIK, uses the same rolling stock on all lines though there may be a couple of different generations of cars in service.

As a Yank, first thought that came to mind was using geolocation by mains hum because you can.

You can…but, won’t the frequency will be stable across the UK grid and these are all in London. Secondly, pretty sure they all use DC motors, so no hum

Loved this! A bit deep to put district and circle as options on the same question. Don’t they use the same rolling stock and cover very similar stations? I found Bakerloo was the easiest to identify.

> Don’t they use the same rolling stock and cover very similar stations?

Same stock, yes.

But stations different. Circle is Zone 1 and so almost entierely covered except for very short sections. But District has a lot of open track sections.
