The eight members of the class entered service on the UR as its MS class in 1913–14. The UR acquired them to carry out shunting and light traffic duties on its branch lines. All members of the class continued in service after the UR was renamed the Kenya-Uganda Railway (KUR) in 1926, and were reclassified in 1929 as the KUR EE class.
In 1949, they became part of the fleet of the KUR's successor, the East African Railways (EAR). The EAR later reclassified them as its 10 class; they were withdrawn in the 1960s.
Preservation
One member of the class, no. 1003, has been preserved, and is on static display at Jamhuri Park in Nairobi.
