Thanks for all the information, very interesting and useful. I was born and lived in Ayrshire until I moved to Rochdale in 1984. I used to travel on this line on visits back to Ayrshire, particularly on the Euston - Stranraer train if possible, as it stopped at Ayr which was the nearest station to my hometown and meant not having to go via Glasgow. I'm a bit too young to remember the heyday of steam in SW Scotland but I can just about remember the last year of the Crabs on the Waterside coal trains. (1966) My dad worked at Waterside and once got me an (unofficial) footplate ride on a Crab from the reception loop to the exchange sidings and back. To a 4 year old, this engine seemed enormous, and I can still remember that smell of heat, steam, and oil that you only get on the footplate. I was hooked on steam locomotives from that day! Anyway, even though I travelled on the GSWR line in the 80s, it just didn't have the amount of traffic that was there in the 60s so I have decided to model it in 1960 when, I gather, almost any kind of loco could turn up! So I'm collecting Duchesses, Princesses, Britannias, Clans, Scots, Jubilees, various Standard classes, Black 5s, Crabs, and even an A3 Pacific! Just need to get the garage cleared and make a start! Again, thanks for all the information.
