'Magic windows' on latest Beijing subway trains

A new smart service system for Beijing subway Line 6 has recently attracted online attention in China.Each window in the front carriage of the train has been replaced with a "magical window" to display the arrival information ahead and the current position of the train, the line network diagram, and a three-dimensional diagram of the next station.Under the system, a number of LED display screens have been installed above the doors and windows of each car. The windows seem normal when the train is stationary, but soon light up and start displaying information as soon as the train starts to move.The “magical window” system has only been installed on Line 6 of the Beijing subway and it will be further improved in the future, according to the operator of the subway trains.(Produced by Yan Yiqiao; video source: Pear Video）
