A day in the life of Shrewsbury's Severn Bridge Junction signal box.
Using a multiple-camera outside broadcast unit the producers covered the action 'live' on a busy summer Saturday on 30th June 1990.
Looking back it is amazing how the trains have changed. There were still loco hauled InterCitys from Euston, loco hauled onto the Cambrian Coast (remember the old Regional Railways?) first generation DMUs in abundance, parcels trains, general freight and even a steamer!
The programme starts with a thorough description of the area and looks inside all three fringe boxes. HTV presenter Arfon then discusses events as they happen with Area Movements Inspector Bernard Hitch.
If you have never visited a large mechanical signal box here is the next best thing.
