As the train was making four stops en route and I had a clear run on the M40, I was just able to get to Haddenham station with a couple of minutes to spare, after seeing the train earlier at Wilmcote. This was an extra run by Chiltern Railways from Stratford-upon-Avon to Marylebone, in connection with the Global Gathering festival at Long Marston. It ran as 1Z23, the 08:10 from Stratford and is just drawing to a halt at Haddenham & Thame Parkway at 09:23, due away again at 09:25. Sunday 31st July 2011. 67013 "Dyfrbont Pontcysyllte" is at the head of the six coach "hybrid" set with DVT 82302 on the rear. Digital Image No. GMPI9872.
