During 'leaf-fall' season the '47' on the overnight 1S25 2100 Euston- Inverness was booked to be piloted north of Perth by a second loco from the 'IIHA' pool. Let's just say that waking up to find 37025 on the front of 47671 "wasn't part of the plan" but that's the way it goes some days. The pair are pictured on arrival at Inverness (11/11/1991)
