Trams in the NSW systems were classed in a unified system covering steam and
electric trams from some time early in the use of electric trams. There was
a previous system for classifying the trailers but I think the motors were
classified by description (eg 10" Baldwin etc).

The system went A = steam tram motors
                          B = steam tram trailers
                          C onwards = electric trams.

All the letters were ultimately used except Q. In addition there were some
other classes such as LP, OP, PR1 and R1 which were for hybrid or modified
classes.
