Seriously 981 doesnt need DDs,Just add 1 more A22 make it 5
buses enough.Those 2 E500s deploy on 167 more better.
Have you taken or observed 981 before? I have seen the DDs on
981 getting very well utilized to the tune of 80-100 pax during its
operating hours. SMRT is very stingy in deploying HC buses - if it
does it is for a good reason.
SBST on other hand is too liberal with its DDs.
I do agree that 167 deserves 2 DDs.
