Per documentation, "If it is impossible to determine the former route of a railway from the ground or through aerial imagery you must not map it." I have surveyed a significant proportion of the area you have chosen to revert, and have personally asked the OSMF on guidance in this area. Per OSMF guidance, I have reinstated edits. Please provide specific examples of areas that contain railways, or remnants or railways, via current aerial imagery or on the ground survey. Railways that go through houses are not considered "still visible".
