A quick calculation suggested that the late running "Cumbrian Mountain Express" would have to be looped in order for at least one service train to overtake. As I drove towards Shap on the M6, steam was visible ahead, so Plumpton seemed a good location. I had no sooner got out of the car when a northbound Pendolino passed giving me a few minutes to wait for 46115 SCOTS GUARDSMAN working up to speed from Penrith.
