This is a huge disappointment and PitA. I got a little out of sequence and thought it was going one be project 3 but #4 would have been fine. Personally I wanted a couple of rakes in Supertrain. Of all the models so lamented on this site.
Absolutely agree, it's' not going to happen. As for Push/pull ....
I'm not sure. That being the case, wouldn't we be more likely to have seen ballasts in original CIE livery, 12 orange bubbles and six with the black chassis, Taras in blue initially rather than bauxite, and I doubt that Supertrain would be preferred above the later IC livery
