Seems like SBS Transit did a few of their own modifications or
made some customisations.
1. Wheelchair-accessibility sticker on front bumper replaced
with standard SBS Transit removable W.A.B. desto on front
windscreen.
2. Offset rear LED display towards the left of the bus, as with
most new SBS Transit buses but unlike a standard Citaro.
I wonder if they will have the visual next-stop display that is
standard on all Mercedes Citaros, and are fitted on all of SMRT's
Citaro buses (though only the production versions have them working
- guess SMRT replaced what was probably the U.K. specification next
stop display with their own).
The EDS display at the rear of the citaro can actually be a full
width EDS, sbst probably opted for the small one and requested to
put it on the left!
Actually the next stop display is also not really a standard
item. They provide the space to install a next stop display, which
smrt did for the production vehicles. Otherwise a standard Bus
Stopping "STOP" light is placed there instead.
