Something interesting I had found on SMRT website..
http://www.smrt.com.sg/tenders/invitations.asp
notice tender number: 7, 8 and 15. looks like they are going to
buy new buses and further upgrading their existing buses on a large
scale...

less new buses, more old buses. >.<
Upgrade the current fleet with a 22 seater bus?? I doubt that it
will be on normal passenger service. More like private housing
services.
With regards on upgrading buses, tenders for bus parts has
always been appearing on the papers. This is more like stocking up
for their maintainance department. Its not something rare to begin
with.
