The GC class entered service on the UR in 1921, and continued in service after the UR was renamed the Kenya-Uganda Railway (KUR) in 1926. The two GC class locomotives were heavily worked as trial engines, and then written off in 1934 after proving the value of superheating. With the exception of the KUR ED1 class shunting engines, all further steam engines ordered by the KUR and its successor, the East African Railways (EAR), were superheated.[3][4]
