Been often told the same thing DJ. In fact I had a chat arguably the man responsible for the change of colour, the head of IE when green Was introduced. Years of the trains being dirty late and unreliable had cast a poor image on the nance CIE which lived in to the livery virtually never changing since the 1960s and 1970s. Besides many still claim that CIE splitting up was possibly the first steps of a possible privatisation attempt like the uk anyway!
think about it. Before the Dart there was the CIE push pull sets. Lovely to look at but anyone who actually traveled on them will tell you yhe 8100s Completley changed the game. And the new branding contributed to its success differintiating from CIE (some would say that stands for Cycling is easier!) and the push pull sets that preceded them
At least we have the retro livery 071 and 073….and possibly more time come
I suppose 112 counts as retro too
