The main intention, is not prevent suicides :( It was meant to
prevent accidential fallen into tracks, like one in Ang Mo Kio who
was engrossed in reading the books and trip into the tracks.....
and died. What a wasted teacher OR cases where personal belongings
such as shoes or handphones dropped into tracks and people go down
to retrieve it back but unfortunately.......
If not, they would just stop building the Duxton (50 storey
HDBs) and similar such.
If no MRT stations to commit suicide, they can always commit
suicide in LRT stations (Excluding Ten Mile Junction) :) OR jump
from a building, be it their HDB kitchen or what.
There are 101 ways to suicide and the best way to solve this
issue is by counselling and not install HHPSD / or stop building
High rise HDBs (Built in on the underground instead, such as a HDB
address of Blk 51 #B14-101?) or ban the sale of knives (To prevent
people to cutting their wrist) or ban the sale of cars (Before
people sniff gas inside a car?)
