As of October 2024, all but one of these locomotives remains in active service with Pacific National, one having been scrapped in 2016 after sustaining significant fire damage.
They were originally to be built at Kelso, but a lack of capacity saw Clyde Engineering lease Australian National Industries' Braemar plant.
The locomotive was subsequently hauled to EDI Cardiff where examination was undertaken to determine the cause of the fire, ultimately being attributed to a fuel leak.
Having suffered substantial damage, the locomotive remained stored at Cardiff for some time before being progressively stripped, and eventually scrapped, in October 2016.
Some variations exist; 8239 has a moustache on the cab for Movember, and 8224 had an RUOK decal on the long-hood briefly when it was in FreightCorp Blue.
