The NZR DC class locomotive is the most common class of locomotive currently in operation on the New Zealand rail network. Primarily employed to haul freight trains operated by KiwiRail, the class is also used for long-distance passenger trains operated by Tranz Scenic and suburban passenger trains operated by Tranz Metro in Wellington under the Metlink brand, and Veolia in Auckland under the MAXX brand.

History

The TranzAlpine, hauled by two DC class locomotives skirting the Waimakariri River
DCP 4818 leaving Port Napier with a freight train in April 2007

The locomotives started life as members of the since-withdrawn Da class diesel-electric mainline locomotives, built by General Motors Canada. Between 1978 and 1983 they were rebuilt as EMD model G22AR, the DC class, with a new cab and upgraded engines. Five were rebuilt at Hutt Workshops near Wellington, the other 80 at Clyde Engineering in Australia.

In December 1998, DC 4588 was shipped to Tasmania for use on TasRail, part-owned by Tranz Rail through the Australian Transport Network. The locomotive was originally leased by TasRail, but has since been sold to them. It was sold for scrap in 2011, after being in storage since 2002.[1]

Technical details

Each DC locomotive has a General Motors 12-645C or 12-645E V12 diesel engine and four traction motors, with an authorised maximum speed of 100 km/h. The locomotive is 14 metres long and weighs 82 tonnes.

DC locomotives are numbered 4006 to 4876 for the Australian builds, 4916 to 4951 for the New Zealand builds. The numbers 4882 and 4899 were not used, so as to start the New Zealand-built DCs in a separate number sub-series. The first New Zealand-built DC entered service as DA564, soon reclassified and renumbered DC 4916.

Locomotive height 3756 mm (12 ft 4in)

DCP Subclass

A subclass of the DC class, the DCP class, was established in 2002 to differentiate the locomotives owned by Tranz Scenic 2001 Ltd from those owned by Tranz Rail Ltd.

The DCP classification was retained on these locomotives after the purchase of Tranz Scenic 2001 by Toll NZ, and continues to be used by KiwiRail. In 2008, DC 4277 was reclassified DCP, followed by 4755 in August 2009 and 4450 in October 2009. In the North Island, the DCP class is used in a general pool of locomotives with the DC class, working both freight and passenger services. In the South Island the DCP class remains in dedicated passenger service. DCP 4663, 4818 and 4945 are leased to Veolia Transport Ltd in Auckland for suburban passenger use.

Auckland Transport

20 DC/DCP locomotives have been leased to Veolia Transport via the Auckland Council subsidiary Auckland Transport. They operate in push-pull mode with Auckland Transport's British Rail Mark 2 SA/SD cars.

Due to an increase in demand during March and April 2011, and an overall increase in rail patronage, the Mayor of Auckland, Len Brown, announced that longer trains would be provided on the Southern and Eastern lines. These trains are configured in sets of four SA cars and a SD driving car with a DC locomotive.[2]

In popular culture

  • DC 4346 (then DC 1582) was seen in the 1981 film Goodbye Pork Pie, towing a westbound freight train over the Midland Line. Attached to the train was the boxcar in which Gerry, John, and the yellow Mini were hiding.
  • DC 4202 was used in the filming of the penulimate scene of the 1982 film Smash Palace. The locomotive was hauling an up North Island Main Trunk freight train, which almost crashed into a Model T Ford containing Al Shaw and policeman Ray Foley. At the last second, the train changes onto a passing loop, missing them competely.
