Was recently in Bideford, Devon and saw that the 210m long* Bideford Railway Heritage Centre track is marked on the 1:25k Ordnance Survey map. I'm uncertain whether it is marked on the 1:50k map. It looks like it is but coincides with other markings and appears to be slightly south of where it should be. Are there any shorter lengths of track marked on OS maps?
