The list of the 11 stations in the Glasgow commuter area and, indeed, three others outwith that area that are within 1 mile of another station is in a document entitled “Rail 2014 Consultation – FACT SHEET - 1”, which was published on 16 December 2011 and which can be found in a link from the publications and consultations section of the Transport Scotland website. It does not sound like a list handed out to somebody at a station.
