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.
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.
