my view on svc 858 :
the route is very long, despite the fact that SMRT purposely
makes svc 858 to make big loops in Sembawang.
A commuter like me from Jalan Kayu will prefer to take svc 168
to get to WRI than taking 858 as it will go to yishun, sembawang,
wasting more time..
I think the only solution to 858's problem is to implement svc
858A for the highest demand sectors, and svc 858 to cut short ?
maybe introduce svc 860 to CGA?
cause 858 this route very unreasonable and long.
