i dun think the 900KUB replace all the merc. it does replace
N113. there are still 280 merc around... and with only 40 new EEV
(from current batch) not yet registered, there is still shortages
of 240 KUB to replace the balance merc..
Let say if we reduce the number of Spare buses in each depot to
25, so can contribute another 125 KUB (by replacing KUB perm with
MK3/MK4 etc), there is still shortage of around 100 KUB. FUrther
SBST have enhanced the frequency by adding buses to a lot of
services.. so technically, 900 KUB is not enough to replace all the
N113/Merc.
At first this is what I think since SBST started introducing
WAB buses on the roads in 2006:-
Correct me if I am wrong.
