There are two major subway lines in center city Beijing. The blue line forms a rectangle/oval shaped loop under the second ring road which encompasses much of the main mass of the urban center. The red line is a line segment that cuts east-west through the center of the city. The Red line stops inside of the blue line oval are the most highly trafficked. Commuters are dense enough that it was deemed worthwhile to build miles and miles of video screens on the inside of the subway tunnels that can be seen from the subway car windows. The frames of the screens are staggered and aligned to the cruising speed of the subway cars so that when at full speed, from the subway car, it looks as if you are watching a stationary television.
We have it in London when you get the Heathrow Express train that goes Heathrow airport - Paddington station directly. These advertisements are awesome
