850 & Gresley support coaches, Skipton-Manchester Liverpool Road (for Great Railway Exposition), Nappa SD858536 
 A 'going away' shot of 850 'Lord nelson' leading two Gresley LNER teak coaches as it descends from Hellifield at Nappa. On the rear of the coach, the headboard from the morning's Cumbrian Mountain Express is seen attached next to the tail light. The coaches were being taken to Manchester Liverpool Road in association with The Great Railway Exposition that was part of the Rocket 150 celebrations in and around Liverpool and Manchester. I am not sure about the heritage of the rear coach here with its observation platform, can anybody advise?
