Locomotives of the Caledonian Railway. The Caledonian Railway Locomotive Works were originally at Greenock but moved to St. Rollox, Glasgow, in 1856. The locomotive classes are listed under the names of the railway's Chief Mechanical Engineers.

Locomotives

The class number used for Caledonian Railway engines was the stock number of the first member of the class to reach traffic. Hence earlier numbered classes could well have appeared later in time.

Until the appointment of Dugald Drummond, unlike most other British railways, almost all engines had outside cylinders, and the 0-6-0 arrangement was quite rare, goods engines being of type 2-4-0 or 0-4-2. Passenger engines were normally 2-2-2.^[1]

Caledonian Railway locomotives still existing in 1923 were taken into the stock of the London, Midland and Scottish Railway (LMS). The LMS built some locomotives to Caledonian Railway designs after 1923.
