It's nearly 22 years since I last had a pair of '47s' in tandem over the Highland Main Line, but here 47804 + 47826 await departure from Perth with Compass Tours' 1Z37 0659 Hereford - Inverness 'Autumn Highlander' land-cruise. The former is restricted to 75 mph because of wheelset issues, and has spent most of the year on the 'Royal Scotsman', but had just been added to the front of the train to act as the spare loco for the weekend (18/10/2013)
