All of the data used from this map comes from free sources, which are publicly available.
This document shows all the opening dates for each of the railway lines depicted in the map. Some areas, including some junctions and chords, were too small to show on the map itself.
Land outlines and regional borders are from the Ordnance Survey Outline Map of the United Kingdom.
Largely come from Apple Maps, and a small number of additional sources. There has to be a timetabled service over the route for it to be included. No heritage or closed lines where included in this map. I would have loved to, but honestly, I had to draw the line somewhere.
