Fascinating in itself, though more impressive is a link within the article to a map of showing the entire National Rail, Tube, Underground, Overground, and DLR lines stations, and platforms in and around London. Oh, and it includes past stations and lines too. The nearest stations at the limit of the map to us in Surrey Heath are Virginia Water, Longcross, and West Byfleet, which shows just how extensive is the coverage of Central and Outer London rail lines.
The map is a creation of French designers at Carto.Metro. Below is a screenshot from the map. Being copyright protected it’s not possible to post the complete map here. You can, though, freely download the map and explore its content at your leisure.
