I believe SMRT would benefit from increased productivity and maybe
even enjoy slight reduction of cost overheads by buying some ADDs.
I think 2 ADDs can replace 3 SD regular buses, hence cutting down
manpower which is getting difficult to find and retain. And I
believe ADDs can carry more passengers than bendies during peak
hours. Also, there are many more seats onboard ADDs hence gaining
more commuter satisfaction. I remember when sv190 was handed over
to Tibs, people started writing to ST Forums to complain there's no
more DDs and now got to stand onboard Tibs buses. If SMRT were to
stick to the principle of using SD regulars for entire fleet, then
LTA should prepare to allocate more parking bays at the future SMRT
controlled new bus interchanges. Maybe up to 4-5 parking lots per
high demand route! And also LTA should prepare to have more
Alighting Bays! Also, are bendies prone to more maintenance
problems than ADDs? The bus operators will understand.
Well, you have mentioned a good and valid point. SMRT do need
ADDs on some of their higher capacity routes, and this is very well
a fact. This is especially so for routes like 969, 851, 190 that do
not have high turnover of passengers.
However, lets see this from a slightly different perspective.
Firstly, their depots are designed to support single decks all
along, this is a problem. Money would have to be invested into new
equipment (e.g. automatic washer, higher loading vehicle
lifts/jacks, maintenance bays to accomodate the higher vehicles,
etc). But this is kind of money must be spent to improve service,
and should not be a deterrent.
However, the issue comes in with regards to what ADDs can they
purchase. In order to have a good cost saving, they should get DDs
that shares components with their SDs unless its going to be a huge
fleet. This naturally points to Mercedes Benz and MAN. MB stopped
producing chassis available for full size double decks after the
O305. As for MAN, their integral DD (the big yellow ones you can
find in wiki) are firstly not available for RHD markets, are too
long (14m), and costs a bomb (nearly 800k each vs. 550k for the
b9tl). As for chassis, im not sure if they still produced any, but
the ones used by KMB are rather dissapointing in performance.
Remaining few manufactuers who produce 3 axle DDs are Volvo,
AlexanderDennis and Scania. Volvo B9TL are good, but the links with
cdge as distributor might be an issue. As for the other two, they
are still relatively unproven here and will cause a overhead on
mechanics training and procurement of spare parts. To add on to
this, they still need to call for tender and see whos willing to
bid for it. Buying a bus is not as easy as going to a shop and
throwing money at the cashier!
