Remarks:
When these engines first arrived from America, they were dismissed as "Yankee Toys". But after they went into service, they proved just what they
could achieve with heavy loads. All were delivered to the South Island where they entered passenger express service and gained a reputation for being 'fliers'. By the mid-1880s, the increasing weight of trains determined their replacement with the more powerful "N' class., but they remained on light duty goods service for a number of years, and after half a century of splendid work the last of these fine little engines was withdrawn in 1928. |
