Actually i am glad it never took place yet. 857 frequency in
city area during peak hours is already quite horrible... if u are
lucky, u can catch another one within 5 mins after u missed the
earlier one... if suay... really can sit there like a idiot for
almost 30 mins and one full-to-the-door 857 will come... followed
by another empty one... 
Yeah... I have no idea why they want to give 857 full WLDEP status
because after all, Suntec/Marina area is closer to AMDEP then
WLDEP; Yishun by right is under AMDEP's control too. Because if
they originally intended to have 857 start from Sembawang, and
after that it did not take place, by right 857 should be handed
down to AMDEP.
