NZR ED class (original) (raw)

The NZR ED class locomotive was a type of electric locomotive used in Wellington, New Zealand. They were built by English Electric and the New Zealand Railways Department (NZR) between 1938 and 1940, and hauled mainly passenger trains on the Wellington region's 1500 V DC electrification, and banked freight trains on the steep section between Paekakariki and Pukerua Bay. The locomotives featured a unique wheel arrangement, 1-Do-2 under the UIC classification system, and incorporated a quill drive (the only type of locomotive to do so in New Zealand) to the driving wheels.
