they do... but they usually deploy more rigid buses on direction
1(CCK to NBR) than on direction 2 during evening time...
so basically, the rigids will be on the opposite directions whereas
bendies would be on Direction 2 by 6-7pm.
but if you noticed,
they send out usually 2 bendies and 1 rigid within 5 minutes at
NBR...
theoratically, what is claimed is that bendies can take in more
than dds by at least 12-15pax... to SMRT, that is a big difference
la...
