DispositionIn service

The New Zealand DSG class is a type of diesel-electric shunting locomotive used in New Zealand. The class shares a central cab design with the smaller DSC class shunting locomotive, and is twin-engined. Meanwhile, the very similarly designed, single-engined DSJ class, has a cab that is offset from the centre.

Introduction[edit]

The DSG class shunters were built in four batches from 1981 to 1983. The first batch of six locomotives was introduced in 1981,[2] followed by batches in 1982 and 1983.[3]

In Service[edit]

The locomotives have seen widespread use throughout New Zealand, particularly in larger yards and for port traffic.[3] They also see service on sections of mainline, performing regional shunt duties in a number of areas.

Livery[edit]

All DSG class locomotives are in the KiwiRail Mark 2 colour scheme (Vertical separations of main colours on car body).[1]
