What I find interesting is how these physical displays handle the inevitable "ghost trains" in the feed - cancelled services that still show as running, or trains that briefly appear in the wrong location. The software problem is messier than the hardware.
If you are less into trains (heresy) but still want to look at unusual maps https://raildar.co.uk/map/KGX is your place to go. its a live junction schematic of any train junction in the UK.
Nice one, OpenRailTimes[0] is a similar style, but split in to smaller local sections by rail company and area.
I also like SignalBox[1] maps for their more traditional geographic layout, and for "less map -- more data", with accurate times that trains pass through stations and junctions, then RealTimeTrains[2] is hard to beat.
