This is the first time that I recorded a photograph of 66953 actually working a train with the only other one that I have is of it in Crewe Basford Hall, see...

As can be seen, it is a train composed of fresh air with not a single box being conveyed, I don't know if this had anything to do with it being terminated at and cancelled from Wembley Yard.
