In operation, the locomotives proved to be satisfactory rather than brilliant and they suffered from occasional gear problems. They were soon displaced from the most important and difficult work by members of the
592:
classes; in fact, later in life, they were re-boilered with A boilers. An improved slightly larger 'Q' type was ordered from
Baldwins in 1914, but classified A due to their dimensions similar to the A class.

In a 1902 trial of various locomotives between
Invercargill and Gore, the Q class with large fire-grate area "gave the most efficient results" of the larger locomotives.
