This is the TrainTicker board running in your browser, with live times from Darwin, National Rail's train information system. Pick any National Rail station and it shows the next trains the way the board on the platform does: times, platforms, delays, cancellations and every stop each train calls at.
It is free and needs no signup. Type a station above, or tap one of the shortcuts, and switch between the classic board and the list of the next three.
It works for every National Rail station in Great Britain, from the big London termini to request stops.
Get it as a real LED board on your desk.
