If people die die want to job on tracks even if install all thos
ehalf ass screen walls on above ground stations will not
help. Only those that have doors that can open together with the
train doors like underground station can prevent that. Another
stupid move to just install barracades with no auto slide doors.
See they just fail to see the problem and the proper solution. I
can tell you install the doors already still will have suicide.
Hire too many foreign civil engineers that think like talented
sheet.
solution very simple. people jump next time just let the train
continue running. until after operating hours midnight then call
the coroner come collect the corspe and body parts - problem
solved. 
Cannot lah. Other passengers see then how, the smell of rotten
body just make people puke. In the end, the cleaners from the
station not only must clean the corpse, after removed by coroner,
but also to clean other people's vomit on tracks or esclators
etc.....
BTW, the HFPSD are automated, such that only trains arrived and
open the door, then the PSD will open. So I dont get what point are
u saying.
