I’m seeing a lack of Asian transit systems, so heres a map of the Chongqing one in central China. I couldn’t find any official one, but I found this really nice one on Wikipedia, but it seems to be designed and made by 云淡风轻. 

Transit Maps says:

This is a nice, simple, no-nonsense transit map that lays out the existing rail transit lines in Chongqing very nicely. I perhaps find the little jog in the Jialing River north of the city centre a little unnecessary (some reworking of the route lines could be able to smooth this out a little more), but that’s a very minor problem. The legend could possibly include the symbol for main-line stations and the aerial cable-car over the Yangtze River, which is included on the map but not explained.

The real test for this map is how it’s going to work when future lines have to be included. Like many Chinese transit systems, Chongqing’s is undergoing almost exponential growth, with four new lines currently under construction (a northern extension to Line 3, new Lines 4 and 5 filling in the numbering gap in the system and a Circle Line), and a staggering twelve further lines in various planning stages. Now that’ll be a map!

Side note: I was interested to see that Lines 2 and 3 are monorail, rather than standard Metro/heavy rail. At a combined length of some 80km (50 miles), it’s the longest monorail system in the world, with the 55km (34 miles) Line 3 being the single longest monorail line.

Our rating: Gets the job done with a minimum of fuss. Three stars.
