PROBLEM TO BE SOLVED: To solve such a problem of defects that the installation of a conventional-installed station platform door that opens and closes parallely is difficult at many stations due to the structure, and moreover, the platform door has its limitations such that a stop position is extremely restrictive due to difference in length or positions of doors of a vehicle, and furthermore, although many applications of platform doors that open and close vertically are filed, any of the facilities are structurally large-scale projects, and besides, speedy escape is difficult in an emergency, and one cannot reach a switch lately adopted for opening and closing the door from the outside of the vehicle.SOLUTION: A large number of bars with height about shoulders of an adult male are stood in the vicinity of a platform at intervals not allowing a person to pass through, thereby achieving separation between trains and passengers on the platform. Moreover, the bar immediately in front of the door is lowered at opening and closing of the door, thereby assuring a passage of the passengers. |
