what is it?

The NZR G class was a type of Garratt locomotives used in New Zealand, later rebuilt as Pacific type locomotives. They were the only Garratt type steam locomotives ever used by the New Zealand Railways (NZR). They were ordered to deal with traffic growth over the heavy gradients of the North Island Main Trunk (NIMT) and to do away with the use of banking engines on steep grades.
