The history of the Volvo B10M with Singapore Bus Services (SBS,
now SBS Transit) began with this bus. SBS9C was purchased by SBS as
a demonstrator back in 1986 for evaluation. It was air-conditioned
and known to be deployed on Service 9, 111 and 118.

The outcome of the evaluation was successful; the rest, they say,
is history. Over 1,000 units in Mk II, Mk III and Mk IV variations
were purchased by SBS Transit, bodied by Duple Metsec and Walter
Alexander. Many enthuasists ride the existing Volvo B10M Mk IV
fleet more frequently as they are retiring gradually. They are the
last step-floored single-deck buses to be operated by SBS
Transit.
So what has happened to SBS9C?
Apparently, SBS9C was exported to New Zealand in 1999. It changed
hands a couple of times between operators in Christchurch. You can
find the records here.
8 years after 2005, is the bus still around?
It turns out that this demonstrator is still alive today.
It is ZH6548 with Nimon & Sons (Nimbus) operating as a
schoolbus, a fate similar to the two articulated buses SBS Transit
has sold (SBS998Y and SBS999U).
This amazing bus has all its decals and badges completely
intact.

Here's the icing on the cake. An amazing video of SBS9C reversing
out of the parking bay:

I hope with this new information you will appreciate the SBS
Transit B10Ms more as you go out to spot them next week.
On a personal note, I have thoroughly enjoyed riding the vintage
O305s, B58s and B10Ms in Australia, and will be uploading the media
on Youtube and my
website when I have some free time.
Finally, I am pretty sure someone will rip this information off
publicly...and that didn't take long.
