what is it?
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.
