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.

By Route
Where trains lose time
Service classes ranked by the share of departures on time. Each row carries the sampled stop count and the average and worst delay.

Provenance
About this data
Every board states where its numbers come from and what they mean, in the one place a reader will look for it.
Source
Official live departures feed for US Caltrain, polled server-side every 10 minutes.
Metric
Per-departure delay in seconds (realtime − planned time).
On time
Delay ≤ 60 seconds. Early trains count as on time.
Late
Delay > 60 seconds · cancelled services tracked separately.
Coverage
The monitored hub stations, rolling ~20-minute window (staggered pulls).
Not an official US Caltrain performance statistic. This board publishes the rolling live window only; extended 7- and 30-day views shown in prototypes are labelled samples and are not data.
Another country, the same reading.
Every board reads exactly like this one — one metric, stated plainly, with its own provenance attached.
