From a staff in another forum:
SMB5888H said to have 320HP engine, same as A22, quiet diesel
engine... and, like what I suspected, it's true the staircase area
has a triangular window same as A39, one of a kind in SG...
For the engine spec, maybe we'll wait and see if it's really
320HP...
The triangular window is just for show...
It's so small that one can barely look out of it.
Unique though.
