The DSG class is a diesel-electric shunting locomotive used in New Zealand.
This class of twin-engined locomotives shares a central cab design with the smaller DSC class shunting locomotive. The similarly designed single-engined DSJ class has a cab offset from the center.
The DSG class shunters were built in four batches from 1981 to 1983. The first batch of six locomotives was introduced in 1981, followed by batches in 1982 and 1983.
These locomotives have been widely used throughout New Zealand, especially in larger yards and for port traffic. They also provide service on sections of the mainline, performing regional shunt duties in several areas.
