Re: S Sets & Airconditioners...

[Robert Harris <bob@fastlink.com.au>]

I think this whole "generation" is wrong. 
What dramatic changes were made to themto make them generational
changes? 
The prototypes were just that, prototypes. 
They were built on the same frame as the first series, recently
converted cars that did not have the yellow insides.
The second series with the yellow interiors had minor changes, one of
which is the raising of the top deck windows and gutter.
I get the "series" from departmental documents.

Going under the "generation" formula that has been suggested here, the
4GT should be more like the 15GT, considering all the different types
getting arround, and I have not even included the single deck sets.
