Great to see another good implementation of rail maps, I do however prefer the opentraintimes layout as its easier to scroll through while reflecting the look of operational systems.
UK rail data is quite open in comparison to this story, for instance check out these live track diagrams (of London Waterloo & many other areas) which show real-time movements of trains. This is how I often find out the platform numbers prior to travel and I also get information before staff during disruption.
