On February 29, I took a press tour of the new No. 10 subway line, which generally follows the path of the Third Ring Road--or will, anyway, once it is built out. For the Olympics, the No. 10 is supposed to only cover part of the loop. The tracks were working by the time the press tour convened; we boarded a train on the west side of the city and rode it clockwise around the north side of the Third Ring Road and down the east side, disembarking in the Central Business District at the foot of the CCTV building. Some of the stations we passed through looked nearly finished, but others had a lot of interior work to go.
In the briefing at the beginning of the tour, we were told that the Olympic part of Line 10 would be open by the end of June. Today was July 1. Along the Third Ring, the station entrances were still gated shut.
