Yeah could try the DDs on 180 because quite alot of pax go end
to end so upper deck will be well used. But personally, I would not
support the use of DDs on 172.
For 172, the heavy loading is only during peak hours and that
explains the split shift bendy slots currently. This Service could
do with an upgrade of some split shift SDs to Bendys. If use DDs
also, probably only split shifts because full day would be quite a
waste. To use DDs on this service, the roads along Jln Bahar and
Old CCK road need to maintain a 4.5km clearance and I would think
it is not too cost effective to for maintainence on such a long
stretch of road for just 1 service and that too just for peak hour
loading. And also I dont believe those people booking out from army
camps will be inclined to go the upper deck with their heavy and
bulky bags. Non Peak hour crowds are only between CCK int and CCK
ave 1 (Quite short distance).
For 184, its more or less an institutional service. Quite heavy
boarding and alighting activity at quite a number of stops along
the route. If you observe 154 along clementi MRT station to the
clementi road stretch, you can already see the situation of using
DDs (its really quite slow). The Bendys on 184 have helped this
service stay efficient. Unless there is a severe space constraint
or there is a ban against bendys, I would support use of Bendys for
this service.
For 189, I am not too sure about the loading after the
shortening of the route. For the Old route, yes, DDs could have
been used but too bad SMRT didnt have DDs before. But for the new
route I believe the heavy loading is just between Clementi Ave 6,
Clementi MRT and the Clementi Ave 1? If yes, it more or less
becomes a kind of feeder service.
Definitely yes to DDs for 172 and 189. I have taken the latter
recently - 2 weeks back and huge loading even after route
shortened.
172 lot of pax board at Boon Lay for CCK. Def must service for
DDs.
184 I agree with you. A lot of boarding/alighting happens at
Clementi MRT. Bendy is a good option here. 154 DDs doing well.
Don't say anything. 154B given DD for a reason. It is not same
situation like 184.
