The Caledonian Railway 294 and 711 Classes (nicknamed "Jumbo") were 0-6-0 steam locomotives designed by Dugald Drummond for the Caledonian Railway (CR) and introduced in 1883. After Drummond's retirement, construction of the class continued under Smellie, Lambie and McIntosh.[1][2]

Ownership changes

All 244 locomotives survived to be absorbed by the London, Midland and Scottish Railway (LMS) in 1923 and 238 survived into British Railways (BR) ownership in 1948.
