Hello.
I have read all the above and I am very interested to see this from the enthusiasts view. I try and make my buses available for people to see them at these events and love to hear the feedback from them.
However very few owners put there bus forward to do these runs. I don't because of the shear cost to run them. FTN 710W will do 18 miles to the gallon on A long constant run. Around the doors 5. R855 PRG will do 20 miles to the gallon on A long run. 8 round the doors.
This said, like last year I am willing to run both buses for A trip each at Durham.
4855 was requested many times to run last Sunday. But it was her very first event and we decided to keep her on show instead.

Like I said before. Some owners don't like anyone on there bus. I don't take that stance. I actively encourage people to come and have A look inside. As long as you ask first.
