158836 leaves Barmouth on 18 June 2005 with the 11:32 Pwllheli to Birmingham New Street Arriva Trains Wales service. Naturally I had not traveled all the way to the West Wales coast  for a Class 158. I had intended to photograph the Pathfinder Tours 'Snowdonian I' railtour, however amazingly this was diverted whilst en-route to run to Blackpool! Although I suppose it does show a surprising amount of last minute initiative, it was a bit frustrating being stuck so far away from the action. Trouble with the loco (37406) meant that Network Rail would not allow the train to proceed to its original destination, due to the remoteness from any potential rescue locomotive.
