I think I see what happened there- it's Sheet Stores Junction (not Sheet
Shores). I Googled on this- sheet stores rail junction and found loads, including for instance this document which 'tells' quite a lot about that whole area:

The rail atlases that others reference are really good- you'll find lots to draw you in, and fill you in. I hope you'll find such will draw you out too to visit such locations.
I recommend the National Library of Scotland Maps where a search on Sheet stores will take you to old and modern maps of the area; you can zoom in.
Google on <real time trains> and input location <sheet stores jn> will take you to times of trains passing there.
Googling on <traksy> and searching on location <+ sheet stores> takes you here to see track layouts and train movements:
