Before talking about the new media that appears in the Beijing METRO lately.
Let's make a short introduction about what is the Beijing metro right now: It
is 10 lines of Metro with the latest opening of the line 4 ( the numbers have
nothing to do with the number of existing lines).
When I arrived in Beijing in 2004 , there were only 2 lines ( Blue and Red).
Then the Line 13 opened a year later and the preparation for the Olympics led
to the opening of a few more. Let's have a look below of what was the situation
end of 2009 for the subway network. ( Many thanks to
