This is what I'm always banging on about, livery-wise. The right logo, right type of lettering / numerals and above all the right background colour are what makes a model railway or even an individual piece of rolling stock not just an accurate model, or a well built model, but something which really captures the atmosphere of what it's meant to be representing.
For years we had no choice but to repaint BR wagons. The livery might be right, but the model wasn't. Then, we got good Irish models. For the 1950-78 period, a large enough stretch of time, the "H" van was something that simply couldn't be done without, as was the corrugated open wagon. Now we have both, plus a multitude of other stuff; the container flat cannot be done without for a 1970s-onwards system.
And carriages - we have everything from kits of GSWR six-wheelers (the MGWR one is a glaring omission, though, as most of the later survivors were of Midland origin) to "tin vans", Bredins, laminates, Park Royals and Cravens, including ready-to-run. The sheer variety would have been absolutely unthinkable even a few years ago. And locomotives! RTR GNR 4.4.0, Murphy Models products.....and "Maedhbh" 800!
Excellent! Congratulations to both model makers and modellers all round. As others have said, Irish modelling is going through a golden age. Long may it last.
