Actually we are dealing with nothing new here. It's what we have
always been updating on sgwiki, but in non-standard form. Bus Body
Codes is just a format that stuck on and followed by other parts of
the world as standard, in databses where a few columns could be cut
off by using this format.
Just use the "Licensed to carry" data for each individual type
and covert them accordingly.
It's just like asking you to shade the options on an optical
sheet instead of writing A, B, C, D. Not a change in syllabus where
you have to relearn everything from scratch.
Body, VIN, chassis type, even the engine number is very easy to
obtain now. Onemotoring has all the information online. No more
boarding of individual bases just to get the numbers. The only
issue is trying to compile it, which can be particularly time
consuming. (but far less so than riding one by one).
