Actually SBST will face this problem earlier than SMRT, given
that they had not purchased any major SD buses after DM3500s in
1997 until the KUBs in 2006.
(And don't tell me that CNGs can operate across the
causeway)
no.... SBST wont face problem earlier than SMRT. there is 50
DM3500 with deregistration date of 25 dec 2017... let say with 2
years extension, can at least last till 2019 christmas.... still
got 9 more years.. by the time, the KUB will be at least 12
years old, time to send it to JB roads already...
