After having visited Ironbridge Power Station, 31145 & 31302 rejoin the mainline at Madeley Junction on 28 May 1994 with the Pathfinder Tours 1Z18 14:56 Caldon Low to Bristol Temple Meads 'Leeky Pot' railtour. Ironbridge was merely a bonus, as the long closed Caldon Low branch was the highlight of the tour.
