I think a few new rules are needed.
After the last quiz, I think it might be an idea that photos of remnants from long closed branchlines are NOT used as a "Where is it". We have a Railway Archeology forum for such things, and it's not really fair on everyone who has no familiarity of a location/area, and what may remain there. I don't mind if people use photos from the past of certain locations (ie: taken in 1962; 1977, or 1985 as an example); as long as the railway was operational at the time, and you hold the copyright for the photo. Also, no cropping of photos as has previously been done by certain people.
