Wuhan, China: A new extension of Wuhan in China happened on 30th of May. This is a city with 8 million people, which is double of what all of Norway in Europe got. The town now got 3 lines, but still the system isn’t done. Line 4 for example is under heavy development from Wuchang railway station to Huangjinkou. Line 2 is under development from Optics into the unknown and Line 1 from Dongwu Boulevard to Jinghe. Interesting to see is that there is no Line 3?

Here is the map of Wuhan Metro and rail lines which goes thru the city:
