Trap-preventing Rubber Bar Added to BJL4 Platforms

A new type of trap-preventing gear - trap-preventing rubber bar was installed at Beijing South Railway Station of BJL4. Added to the edge of the platform, it can effectively narrow the gap between the platform and the train, prevent passengers or luggage from trapping when they board or alight the train.  After a period of trial run, it will be applied to all the 24 stations of BJL4 if proved good performance.
