I'm quoting this post from a few days ago but anyway:
Did anyone really think that Sv 169 will get DDs? Sv 169 is like
the unoffical "Army Express". Go and count the number of army camps
& key protected places it passes by. (Khatib Camp, Dieppe
Barracks, Nee Soon Camp, Sembawang Air Base, Sembawang Camp,
Sembawang Wharves, Sembawang Shipyard).
If they really put DDs on Sv 169, don't you think that the
authorities would think that this would allow random people to
happily spy into what goes on in the camps because of the elevated
height? And in turn pose as a security threat?
I'm not saying that Sv 169 will never get DDs, but I don't think
it will happen anytime soon on their priority list.
I do agree that Sv 169 needs much more Bendies though in the
fleet at the frequencies they're running now during Peak. The
Rigids just can't cope that well unless they're bunched up
together.
If you are thinking like that, let me ask something: Did 169
plied these areas during its SBS days? It already has DDs that time
and the same thing you mentioned could have applied back then.
