Freight on this line, hour by hour

Freight is booked over the South West Main Line on 997 paths in the week beginning 12 October 2026: 186 paths on the Wednesday, 77 paths on the Saturday and 4 paths on the Sunday. 111 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 13:00 to 14:00 on the Wednesday, with 30 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.

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.
