I'd like to see Mexico City Metro, specifically "Line B" with those old MP68 (Matériel roulant sur Pneumatiques 1968) designed by Alstom in France. It is the second largest metro system in North America just behind the New York City's Subway, it deserves being in this game as well. In 2016, the system served 1.662 billion passengers, placing it as the ninth highest ridership in the world. Line B and its own 21 stations. MP68 in France before being delivered. Fact: This train number "01" called "The Presidential" is still operating in Line B.
But the global population is 7.7 billion people. Those trains must be pretty overcrowded. https://en.wikipedia.org/wiki/World_population That means the entire worlds population has travelled 200 times on the Mexico subway in one year. wikis whacky maths perhaps.
Looking at the OP (and the wiki) it's 1.662bn- only three orders of magnitude out though. (I thought it was a comma at first glance too.)
Indeed- that did occur to me before I had a second look at the OP. It's largely a European practice I believe.
Yes, depends on what a billion is, either a thousand million or a million million. So according to the stats on the link below there were 1,394 million passenger journeys on the London Underground 2017/18. I can believe that having used the tube many times, they were all on the same train as me. https://tfl.gov.uk/info-for/media/p...ssenger-numbers-on-london-s-transport-network
You're correct- it is now internationally recognised (since the '70s I think) that a billion is a thousand millions, a trillion is a million millions etc. To me a billion being a million^2, a trillion a million^3 and so on makes perfect sense- a thousand millions used to be called a milliard though that could easily be misheard as million. The change seems to be an Americanism that caught on- or (perhaps more likely) the rest of the world just gave up trying to explain it to them. Using the original billion 1,662bn would be 1,662,000,000,000,000- that's a lot of passengers.
