I have started to map all the old railway lines, tramways and mineral railway lines in Ayrshire and Glasgow and facinated how many lines there used to be.
This would be a great project for others to get involved with.
The map I am using is the OS County Series mapping at Six-Inch to the mile / 1:10,560 for the 2nd edition, dating between 1888-1913
Anyone wanting to help get in touch, maybe we can expand the area once the inital area is complete.
The good thing about using OHS is its specifically for subject concerned and not a mix of things that are not of interest.
Yes, roads and the occasional building can be added but main objective is to record every single rail line and once complete have a slider view with google/bing that can overlap and compare old and new.
