Once upon a long ago this used to be a railway line. When it was removed I have no idea but I believe it is now the cycle path you are referring to where the teenage girl's assault took place. I believe this path is easily accessible from numerous places along it's path but I've only used the postmentioned asset so don't quote me. Interestingly, as I did the "walk" on Google Earth from Claudia's place to the University, just before Melrosegate Bridge, I passed by a bus coming out of one of the side streets with "University" written as its destination and a bus stop just prior to the bridge. I wonder how early this bus runs and if it runs directly to the University. Just dotting 'i's and crossing 't's.
