The problems lies with the rolling stock, not the viaducts.
What's wrong with the viaduct? Anyway, did you know the BPLRT runs
on 600V AC, not traditional DC used with most third rail?
Actually, to me both are also sucks.
Look, there is no rolling stock in any where in the world with
100% perfect no errors ever since they were in operations. So we
must be prepared should any glitches happened. Now, if Sengkang /
Punggol LRT were to have glitch (I have witnessed a Car 04 stuck /
blackout in Sengkang station in 2004 or so (In clockwise direction
1, 2, 3....) , and thus only the anticlockwise direction was
available, meaning 5, 4 , 3...... which I happened to see the
signal for the clockwise was pointing towards Cheng Lim since I
started my journey from SE1. The time of incident was at 8pm or
so), anyway, they can do a safe emergency evacuation because people
wont fall on the roads so easily (Unless suiciders on LRT), but in
BPLRT, you cannot do so, because there is simply no barrier to keep
you from falling and in my point of view, one can fall down easily
and any such incidents will means people must walk extra carefully,
as if they are participating some kind of MOE adventure parks'
camping where Sec 2 campers went to walk to "narrow wooden plank"
in a height of X meters. (Ok, some others got a chance to play
flying fox etc, OT)
If the BPLRT does not fail so easily AND the alignment of BPJ
MRT is good and nice, I am sure I like this system. But sad to say
it is not and I just hope it can get a rebirth.
