On a more general note, how did the day go? I was looking forward to it for months, thinking it would be like the old "Steam on the Met" days where there was a two train service, headed by steam in each direction with three locos, one on each train and one resting. Admittedly they had a Class 20 or Sarah Sissons in each consist, AFAICR to provide air braking. The Steam on the Met days were good value and provided a great afternoon's entertainment.
Then I saw this year's programme

Only one train and only steam hauled in one direction. And then I saw the ticket prices.

. Decided not to go in the end, had an excellent afternoon with the family at the Herts County Show instead for a fraction of the cost.
