37138 slowly approaches Jersey Marine South Junction on 28 July 1991 with the Pathfinder Tours 1Z81 06:28 Liverpool Lime Street to Onllwyn 'Vulcan Valley Venturer' railtour. Hiding under the bridge are 20106 & 20113, which would shortly be taking the tour up into the valleys. The train is on line from Dynevor Junction, and has just passed under the M4 motorway. Just out of sight to the left of the pond is the line that will take it back north to Onllwyn, and further over still is the other chord from Jersey Marine South Junction, linking (appropriately) to Jersey Marine North Junction, only a short distance west of Dynevor Junction, where this train diverged. I hope you're following this!
