Late Trains/Guides

Guides and notes

How to read a timetable, what the delay figures on this site mean, and how they are measured. Written from the archive, and short on anything we cannot show you.

Where our train delay data comes from
Every figure on this site traces back to something we recorded at the time. This explains what we collect, how an arrival becomes a recorded arrival, what we do when we cannot tell, and why some pages show nothing at all.
