Many thanks, Patrick.
Some were done by Kevan McIntosh who made a lot of them up for me. I will ask him what colours he used. Others were done by me, by simply rubbing a random mix of very pale brown and grey weathering powders rubbed into cracks, just as general muck will collect in real life, and then very lightly brushing more (dry) round the chassis, rooftop and lower ends.
Many thanks, Noel. More you be done, of course. Still haven’t started buildings, which will be the sort of corrugated-sheet structures seen on lines like Kenmare, Valentia and the west Cork system.
So many, indeed; including relatives of mine too!
