DDs for SMRT?
Possible... next 10 yrs loh...
(Some ints and the depots are still not ready for DDs,
furthermore mainterence is another matter)
Next 2 to 3 years will do.
Only current SMRT Woodlands depot looks not ready for DDs.
Kranji is shifting and there will be a new one for Woodlands too,
so hope they will be DD friendly. Ang Mo Kio is DD friendly too but
think its lease is going to end soon.
Bus interchange, only Yishun is not ready for DDs but Yishun
interchange is going to tear down soon and so the new one is going
to be DD friendly. The rest of the bus interchanges under SMRT are
DD friendly.
Maintanance for DDs should be easier than bendies.
