Rope-Type Screen Door systems (RSD)

* Each of train door must corresponded with each of PSD door.
* The gap between a train door and PSD door must be within the range of tolerance of stopping position.
* In general cases, the range is ±250mm (a train door open width : 1300mm, PSD open width :1800mm)
* In case of over-shoot and under-shoot, EEDs might be necessary.
* RSD has the position of the posts, not the positions of doors.
* It does not matter what kinds of trains and its stopping position at the same platforms.
* RSD stands for Rope type Platform Screen Door.
* It is one of the types of PSDs, but it has specialties.
* Because of the specialties, it overcomes the limitations of PSDs.
