Anyway, took this on SBS8454 on svc 24.

Note the additional poles on the top of the stanchion poles.
Looks like additional structures to hold the existing stanchion
poles to reduce the vibrating effect. Looks like AMDEP is trying to
do some improvements in the interior now.
However, it doesn't seems to work very well as the stanchion
pole beside the first PIW rest as it is still vibrating while
moving. Mr Tamago, please take note of this.
Hope that the EURO IVs can also remove one PIW area for more
seats.
Took SBS8580 on svc36 last week. Overall the EURO Vs are
better than the EURO IVs, and can hear the faint turbo whistle
sound, reminds me of the old N113s. The engine noise sounds
"heavier" than the EURO IVs. But what pissed me off is the stuffy
air con. Hope that they tweak it to make it better.
Is the air con on the EURO Vs by Sutrak, since the on roof
air con pod looked like the Volvo B10M MKIV DM3500's type???
Chin-up bar 
I agree to the idea of removing 1 PIW area and add in 3 more
seats there. Furthermore not many wheelchair-bound passengers tend
to take bus. And another thing is that most of the WAB buses are
deployed on the non-WAB routes where drivers don't even let
wheelchair passengers board though there are the WAB features. So
what's the point?
Perhaps luggage racks should also be introduced on those Scania
K230UBs which are deployed on the bus services that goes to Changi
Airport.
Btw is it possible for SBST to add in a granny seat to all the
Batch 1 K230UBs??
