I refer to this sentence from the press
release
"The MAN A22 also has a first of its kind Sliding Plug Exit Door.
This unique door
swings out from the bus body then slides open, enhancing
passenger safety
as it prevents passengers from accidently being hit by the door
as it closes."
For the uninitiated, this type of door has been in use for london
bendys for a while back...
so it IS NOT FIRST OF ITS KIND
ACx
probably SMRT means the 1st in SG..
