Jamie, this looks as if it will be absolutely brilliant! I remember Green Ayre well and worked there on secondment from Lancaster Castle station in the mid 1960s, walking down the linking track, which was a designated walking route.
My friend Edward Meadowcroft sent me this link. he used to arrive at Green Ayre for school every day throughout the 1950s , often popping into the sheds to see what was in.
I have several photographs of Green Ayre. You probably have many images yourself, but I will be happy to email you what I have if it will help your project.
My email is;
owlpub@hotmail.com
I look forward to seeing some images on this site as your project progresses.
Good luck! (And a lot of hard work too.)
Best wishes
