CR 264 Class

The Caledonian Railway 264 Class was a series of inside-cylinder 0-6-0 goods locomotives designed by Dugald Drummond and built at St Rollox Works, Glasgow, from 1885, constituting a variant or development of the 262 Class goods engines that entered service in the same year. Like the 262 Class, the 264 was a practical working goods engine intended for Caledonian Railway coal, mineral, and general goods traffic, following Drummond's characteristic design principles of inside cylinders, straightforward boiler design, and Westinghouse air brakes.

The distinction between the 262 and 264 Classes was a matter of detail specification — minor differences in boiler dimensions, valve gear, or cylinder measurements — rather than any fundamental design difference, and both classes worked CR goods traffic side by side throughout their service lives. The Caledonian Railway maintained a complex numbering and classification system for its goods engine fleet that reflected successive builds and modifications, and the 262 and 264 classes represent adjacent entries in that system rather than substantially different types.

None of the 264 Class was preserved. Like the overwhelming majority of Victorian goods engines, their service was useful and unobtrusive rather than celebrated, and they left the railway without fanfare.
