Ah, I forgot about the catering staff - thanks!
I wasn't aware the Borders line was to have a trolley service, it's not specifically mentioned in the agreement anyway. Also food boxes are to be available to scenic passengers on all services except the Borders by the looks of it. Tablecloths and everything if you please.
I think there are probably going to be 2 levels of Scenic train provision.
The full on singing dancing bells on version on the core lines of West Highland and Kyle which were the requested lines from TS in the ITT.
A slightly reduced version with less fancy catering, tablecloths etc on Borders, Dumfries, Stranraer and Far North line.
It's difficult from the ITT to work out exactly who'll do what when. I presume the easiest way to comply with the franchise requirement for tourism trained staff is to train all guards and catering staff on these routes to Tourism SVQ standard.
Then on non trolley services the Guard acts as the "Tourism Ambassador" while on existing trolley services it will be the catering staff.
Seems a sensible approach really to try and roll out the tourism success of the West Highland and Kyle lines to other areas while acknowledging that they aren't there yet.
