Operation and Improvement
In their early years, the B class hauled freight trains between Christchurch and Dunedin, with their pulling power a considerable asset. However, they did not last long on this task. In 1906, the A class was introduced, followed by the ubiquitous AB class in 1915, thus displacing the B class locomotives to branch line trains, and in later years, shunting duties.
In later years, four of the Addington-built members of the B class received upgrades. The first to be upgraded was B 306, re-entering service in March 1930. The overhaul involved the installation of wider fireboxes and superheated boilers, increasing the boiler pressure to 200 psi and generating a tractive effort of 21,200 lbf. B 304 was similarly overhauled in 1931 and B 307 followed in 1935, and then a considerable length of time elapsed until B 303 in 1948 became the fourth and last to be upgraded.

Famous quotes containing the words operation and/or improvement:
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
“We are more thoroughly an enlightened people, with respect to our political interests, than perhaps any other under heaven. Every man among us reads, and is so easy in his circumstances as to have leisure for conversations of improvement and for acquiring information.”
—Benjamin Franklin (1706–1790)
