Both deserve DDs but not too much. 186 packed on AM Peak Hour so
2 DDs should suffice. 97 packed on peak hours, maybe 5 enough oredi
liao, scarly all LO3X better...
186 needs the 4 DDs. Please see the load towards Shenton Way at
River Place Condo between 8.30 and 9.00am. You cannot enter the DD.
And 4 DDs are plied back to back because there is huge load. It is
true that apart from these timings, 186 does not have DD deserving
load. Hence, they should crossover to another route in the other
hours.
97 loading is at MBA, Harborfront, Alexandra Road but only
between 5.45pm and 6.45pm. Apart from this, you will see seats in
SD to sit. Hence, you are right around 7 DDs on 97 should
suffice.
