All freight movements over Britain's rail network are monitored and controlled by an advanced computer-based system known as TOPS (Total Operations Processing System). The film follows the progress of a wagon load of equipment from Truro to the Midlands and shows how TOPS makes it possible to accommodate a last minute change of plan.
