Don't think so, but you can check on YouTube,MistaSGW's video.
He has the video first hand. When I passed by there, the passengers
have all alighted already and two two trucks have also
arrived...
TIB546A deregistration date is 21 Aug 2014, which is just less
than 3 months away...there is a chance that SMRT may just lay up
the bus..unless they are willing to give it a new engine cover like
TIB1113J for its last 3 months in service. Whereas TIB552G i guess
its 50-50 since its deregistration date is 24 Feb 2015 but it may
end up like TIB734Z...
