Thats right. To go deeper, the old convention was engine
position x engine displacement x generation x chassis type.
Some folks in Hong Kong did ever go into naming the K310UD (ASU
1) as K95UD when it first came out, in older sources this can be
found but now they have went to the new designation.
So for the L94UB, L113CRL, N113CRB, it would have been like:
L94UB - L: Longitudally mounted engine, 60 degrees angle, 9: 9L
engine, 4: 4th Gen, UB: Urban citybus
L113CRL - L: Longitudally mounted engine, 60 degrees angle, 11:
11L engine, 3: 3rd Gen, C: 2-axle single decker, R: RHD bus, L: Low
entry
N113CRB - N: Transverse engine, 11: 11L engine, 3: 3rd Gen, C:
2-axle single deck, R: RHD bus, B:Regular non-low-floor bus
Did I get it right?
