The map's my doing! And hence why it has a Cotswold Line-influenced name. It's not abandoned, I've just unfortunately not had much time to work on it of late. There's another update covering the Pennines which I hope to post in the next couple of months. Never enough hours in the day...
Richard What an excellent map. The way open and closed lines are shown is really clear.
It must be a major project, and keeping it up to date will be non-trivial either. You may wish to note that the Vale of Glamorgan and Ebbw Vale branches now carry regular passenger services, as does the Swansea District line which provides an alternative way to get from Port Talbot to Llanelli avoiding Neath and Swansea.
