LMS Stanier Class 5 4-6-0 5110
London Midland and Scottish Railway (LMS) Stanier Class 5 4-6-0 No. 5110 (British Railways no. 45110) is a preserved British steam locomotive. It has carried the name RAF Biggin Hill in preservation, though it never carried this in service.
5110 was built in 1935 by the Vulcan Foundry. She was built with a low-degree superheat domeless boiler. It still carries a domeless boiler. It was one of three members of the class to haul the 'Fifteen Guinea Special', Britain's last steam-hauled passenger train, on August 11th 1968. It was then preserved, and has since been based on the Severn Valley Railway.
