Network ranks every stopping point by how much delay it puts into the rest of the country. Not how late it is, but how much lateness starts there and travels. Click a station to see where its delay ends up.
Replay plays a single day back. Every dot is a real train at its recorded position, coloured by how late it was at that moment.
