Caledonian Railway 294 and 711 Classes

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.

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.

Numbering

 * 294 Class
