Reading the board
Four numbers summarise the rolling window. The same metric is then broken down by delay bucket, by route and by station.
Delay Buckets
How late, and how often
Each departure falls into one bucket by its delay. The bar shows the share of departures in the current window.
Trend
The window and the days behind it
The live window alongside the day-by-day record this board has published since it went live.
