Freight on this line, hour by hour
Freight is booked over the Hertford Loop Line on 327 paths in the week beginning 12 October 2026: 51 paths on the Wednesday, 73 paths on the Saturday and 2 paths on the Sunday. 20 of them run whatever the traffic; the rest are held in the timetable and used only when there is something to move. The busiest hour is 04:00 to 05:00 on the Saturday, with 12 paths booked.
The grid counts the goods trains booked to pass in each hour of the week beginning 12 October 2026: the darker the hour, the more paths, and a dot marks an hour with at least one path that runs regardless. Engineering trains, empty stock and light engines are not counted. Across Britain only about a fifth of booked freight paths run on a given day, so a booked path is a possibility rather than a promise; the freight statistics page explains how that is measured.

Lines it meets
Passenger figures are the Office of Rail and Road's estimates of station usage for 2024-25, added up across the stations on this line. They count entries and exits at those stations rather than journeys along the line, and a station served by more than one line is counted for each of them.
