Actually it was Andy who wrote that.

But "REB" is unlikely to sound much different to "red" over a
two-way radio either. Whatever happened to the phonetic alphabet?
If they used that the message you suggest would become "I'm at a
green signal at Romeo Echo Delta"; a far more comprehensible piece
of communication!

Very true! But are these codes used in radio messages? If so, why are
Northfields and Arnos Grove drivers allowed to use different codes?

I can only speak for the Picc, but abbreviations are only used as a form
of shorthand in written communications (duty books, DMT's instructions
etc.) and stations are always referred to by their full (well, often
missing Lane, Grove etc., so we just refer to Arnos or Acton) over the
radio.
