Hi Daniel,
The young lady is an actor, we do have some lady members that are drivers. The locomotive is petrol hydraulic with vacuum brakes. The young lady was a quick learner having had about 15 minutes tuition. It isn't a difficult locomotive to drive, there were no other trains on the system and she wasn't driving over any of the grades. With a loaded train and wet rails it can be difficult to stop exactly where you wish. We have two open days as it is a Bank Holiday this weekend, maybe we should have asked her to come and play.
Take care Tony.
