Curious description of coaches by Rails of Sheffield

Rails can be considered box shifters and for me they've always been the best. Speed of delivery, prices and quality of products as good or better than any other supplier. However, today received a promotion email re their Rapido Evolution coach range which are described as "prototypically literate" models. Not quite sure what this means, can only guess that the models ability to read and write matches that of the original ones on the railway.
Does anyone have a better interpretation ?

This phrase has as far as I know its origins in Hatton's 4/6 wheel Genesis coach range.

Both the Genesis and Evolution ranges are generic i.e. not models of actual prototypes.

But they are supposed to incorporate actual prototypical features while still being generic hence the use of the phrase "prototypically literate."

There are several threads over on RMWeb which go into this in way more detail .

For example, try this one.

Did read that thread not long after it was started, even went as far as to pre-order 3 of the LNWR coaches, however cancelled them as decided to build PC models versions instead, although was half way through the first when bought 4 Ratio ones off ebay - the sides were lined and base shell complete at £27 for the lot. That was a bargain.
Didn't see the phrase "prototypically literate." but understood and accepted generic.
