Roaming the length and breadth of the country the Chief Engineers New Measurement train has a fortnightly timetable to cover the main lines, with the exception of the southern region. Formed of former HST power cars and a number of test coaches the train looks for track defects and imperfections before they become problems.
On its fortnightly survey of the East Coast Main line and diversionary routes the Chief Engineers New Measurement Train passes through Watton-at-Stone.
