From Metro Line 1 to the airport rail express, the “seven color rainbow” team of Hangzhou Metro has been growing in the past decade. What color is used for each subway, and what development has the vehicle and speed experienced? Let’s learn about it today~
Hangzhou “colorful” subway
The color of Hangzhou Metro is called “seven rainbow”. The first seven lines of line 1, line 2 and line 3 correspond to seven rainbow colors: red, orange, yellow, green, green, blue and purple. The later route is deepened or highlighted on the basis of the first seven lines.
These different colors are not only marked on the train, but also on the corresponding station platform. What color does each subway line correspond to? Let’s have a look!
