With the Kirkby Thore gypsum works prominent in the background, 47823 S.S. Great Britain heads north over the Settle & Carlisle line on a very dull 5 February 1994 with the Rail UK 1Z36 07:51 Peterborough to Carlisle 'Settle Carlisle Thunderer' railtour. The Kirkby Thore works produces plaster and plasterboard both from locally quarried gypsum, and more recently from the synthetic gypsum produced by the flue gas desulphurisation process used at certain coal fired powered stations, principally Drax. Although the weather is bad, it looks like it is even worse further south, judging by the carriage roofs!
