With the Newport transporter bridge just visible through the drizzle in the background, 40122 (D200) approaches Park Junction on 23 May 1987 with the Pathfinder Tours 1Z37 Crewe to Ebbw Vale 'Gwent Valley Explorer' railtour. The tour also visited Barry Island and Machen, working top'n'tail up the branches with 37280, with the exception of the Machen line where 37220 was used. The line the loco is on here leaves the mainline at Gaer Junction, whilst the lines in the background come from Ebbw Junction, thus forming a triangle.
