www.video125.co.uk the UK's favourite railway film producer took a 'live' outside broadcast unit to Shrewsbury to record a day in the life of the largest surviving mechanical signal box - Severn Bridge Junction. With trains coming in from three main routes, it takes two signalmen to man the box. Presenting the programme is Arfon Haines Davies. He and Area Movements Inspector Bernard Hitch comment on the activities as they happen. Oh, the date, by the way, was 30th June 1990 - a busy summer saturday in which we see classic BR trains come and go. First generation DMUs, sprinters, class 47 hauled InterCitys, class 37 hauled Regional trains, freight, parcels units and even a steam excursion. So much variety and now so much of an archive. How much does this all cost? A tenner, that's all. Ten quid including VAT, postage (within the UK) and packaging. There is even a money back guarantee, but we bet that you will watch this more than once.
