NZR DA Class
The New Zealand Da class diesel-electric mainline locomotives operated on the New Zealand railway system between 1955 and 1989. With 146 locomotives, it was the most numerous class to ever operate in New Zealand, with five more than the AB class steam locomotive.
The class were A1A-A1A versions of the Electro-Motive Diesel G12 model, with the design altered slightly to run on New Zealand's 1,067 mm (3 ft 6 in) Cape gauge rail system, and fit the small loading gauge. They were introduced between 1955 and 1967, and were the first class of diesel locomotives to seriously displace steam traction.
Between 1978 and 1983, 85 were rebuilt as the DC class, of which many are still in use. All but one of the remainder were withdrawn by 1989, with six preserved. The last locomotive was refitted for shunting duties, becoming DAR 517.

Famous quotes containing the word class:
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
