Ok, cant find something related to this... but some of SMRT's MB
o405s have undergone a minor refurbishment.
So how minor?
1. Emergency exit sealed from inside and outside, emergency handles
on both side of the door removed. Emergency door window sealed with
new "window frame".
2. Two windows on the driver's side of the bus used as emergency
exits instead, (the 2nd window and the window after the emergency
exit) Two new emergency hammers provided and attached on top of
door bells.
3. All aircon panels (the green panels on top) cleaned.
4. Side panels (beside the chairs) are repainted.
5. Windows ledges and corners cleaned.
6. Unknown device installed on the celling on top of the rear door.
(not all have this installed)
