national express East Anglia (NXEA) railway punctuality

The following is an analysis of the punctuality of national express East Anglia railway Mainline services between Witham in Essex and London Liverpool Street station. Most of my journeys these days are between Witham and Stratford, with occasional trips to Liverpool street and very occasional other intermediate station trips.

The statistics below represent my journeys taken between 24/07/2006 and 14/11/2011. I recorded the actual arrival times and these are then compared to the scheduled times in the national express East Anglia railway timetable.
