Remarks:     Although primarily built for suburban duties, this class saw main-line service in the Taranaki district. Most of the class, however, were assigned to branch-line and local services, and for many years, the suburban runs from Christchurch to Lyttelton. They were also scattered far and wide throughout the country and were a very handy locomotive. Two were experimentally converted to oil burners in 1909-1910. Tests were satisfactory but coal was much cheaper than oil at the time.
