The problem is that 27A and 27B is operated using 27's buses.
There cannot be 27A perm buses, only 27/27A buses. That is the
trouble.
Exactly my point. 27 has like 27 SDs deployed on it.
18 SD should travel to Changi Terminal, and 9 DD should be
permanent and return from Tampines Ave 4/5.. Anyway, the max load
is there. That way peak hours the clearance will be very good.
