After visiting Pontycymer, 37212 pass Tondu on 4 April 1992 with the Pathfinder Tours 1Z16 06:05 Manchester Piccadilly to Ebbw Vale 'Hoovering Druid' railtour. 50033 Glorious & D400 are way out of sight to the right, on the rear of the train. Some track rationalisation had taken place since I visited this location a year earlier for another Class 37 railtour.
