A perplexing stats page compares 161 different Metro networks. While the page is heaped in spoilsport caveats about what constitutes a Metro system, it is fun to play with. For what it’s worth, here are a few categories in which London excels.
London has the second oldest network (1863), beaten only by Mumbai (1853).
London is easily the world’s longest network, with 421 km of track.
We come second to New York for number of stations, however (468 versus 382).
All in all, you're left thinking there's an awful lot of Tube out there.
Thanks to reader David Warwick for the tip.



The 1953-date is interesting, becouse:
"India's first railway line opens to link Bombay with Thana 20 miles away. English engineer James J. (John) Berkley, 34, has built the line and will complete the Bombay(Mumbai)-Calcutta-Madras-Nagpur line in 1856."
They hadn't got railway in 1853.
Interesting.
