Locomotives

DB class

Subclasses: DBR
Number range: 1018-1174 (DB), 1199-1295 (DBR)
Entered service: 1965 (DB), 1980 (DBR)
Power output: 709kW (DBR)

The original DB class was built from 1965 to 1968 as a lighter version of the DA class, intended for use on lighter branch lines and the East Coast Main Trunk through the Karangahake Gorge. Ten units were rebuilt as the DBR class from 1980 to 1982, three of which remain in service. Two locomotives were leased to Auckland Transport from 2003 to 2014 for use on the SX carriages.

DBR 1226

Tip: The DBR class and the DC class are very similar, however the DBR has a small platform behind the long hood which the DC lacks. The best way to tell these classes apart is by looking at the number.

DC class

Subclasses: DCP
Number range: 4006-4951
Entered service: 1978 (as DC class)
Power output: 1,062kW (645C), 1,230kW (645E)

Rebuilt from the DA class between 1978 and 1983, the class is still in use today, currently in use on both freight and passenger services. Out of the original 85 locomotives built, 45 remain in service. The DCP class originally denoted locomotives owned by Tranz Scenic 2001 Limited, but now denotes those locomotives fitted with bogie strops to prevent the bogies separating in a derailment. The class is slowly being phased out from service.

DC 4415
DE class

Number range: 1308-1458 (TMS), 501-515 (original)
Entered service: 1952
Power output: 490kW

Approximately half of this class of 15 locomotives remain today, with one in service for the Taieri Gorge Railway and the rest in preservation. DE 508 was once part of New Zealand Rail's Heritage Fleet.

DE 507
DF class (1979)

Subclasses: DFT, DFB
Number range: 6006-6317 (DF), 7008-7348 (DFT)
Entered service: 1979 (as DF class), 1992 (as DFT class)
Power output: 1,230kW (DF), 1,800kW (DFT)

The DF class was built as a modern version of the DC class, sharing the same prime mover, but with a Co-Co wheel arrangement, enabling the class to make greater use of its power. In 1992, DF 6260 was turbocharged and altered, and re-entered service as DFT 7008, with the other 29 locomotives following later. DFB class locomotives are a standard DFT fitted with the BrightStar wheelslip control system.

DFT 7145

Tip: Note the upper headlights. The DF class's lights are one over another, while on the DBR, DC and DX they are horizontal. Also, all DFTs and DFBs have a small chute behind the cab on the left side of the locomotive (not visible in this photo).

DH class

Number range: 2816-2866
Entered service: 1978
Power output: 672kW

Originally an order for Philipphine National Railways, they were purchased by the NZR as a heavy shunter for Auckland port work. They are still used in Auckland and Tauranga for heavy shunting, now fitted with multiple-unit capability.

DH 2845
DJ class

Number range: 3009-3689
Entered service: 1968
Power output: 672kW

Introduced to the South Island to replace steam locomotives. Their Bo-Bo-Bo wheel arrangement gave them an advantage on lightly laid branch lines, and were also suitable on mainline runs. The class was used on the Southerner passenger service in the train's early days. Today, six remain in use by Taieri Gorge Railway.

DJ 1209 (DJ 3096)
DL class

Number range: 9008-9515
Entered service: 2010
Power output: 2,700kW

Purchased by KiwiRail and first delivered in 2010, these were the first brand new locomotives to be introduced since the DF class over 30 years previously. Currently the most powerful and common diesel locomotive in New Zealand, the class sees service in the North Island on heavy freight trains. 48 locomotives from three batches are currently in service.

DL 9354
DSC class

Number range: 2000-2759
Entered service: 1958
Power output: 315kW

Purchased as a heavy shunter to replace smaller DS and DSA class shuntimg locomotives and smaller steam locomotives. A second version was built by NZR powered by two Leyland diesel engines instead of the Rolls-Royce engines. Only NZR-built locomotives remain in service. Two locomotives are preserved, one by Waitara Railway Preservation Society, and one by Mainline Steam.

DSC 2244
DSG class

Number range: 3005-3304
Entered service: 1981
Power output: 700kW

The DSG class forms the basis of KiwiRail's heavy shunting and yard work. All class members remain in service, and is the first class to achieve an all-KiwiRail branded fleet.

DSG 3264
DSJ class

Number range: 4017-4060
Entered service: 1984
Power output: 343kW

This class is essentially a single-engined version of the DSG class. The first locomotive was imported assembled in 1984, with the remainder assembled at Addington Workshops. All class members remain in service.

DSJ 4004

Tip: All of the shunters look similar, but note the headlights. On the DSC, the headlights are part of the body, while on the DSG and DSJ, they are mounted on a small plate above the body. The DSJ class has an off-centre cab.

DX class

Subclasses: DXB, DXC, DXR
Number range: 5016-5520 (DX), 8007, 8022 (DXR)
Entered service: 1972
Power output: 2,050kW (standard), 2,460kW (uprated, some members), 2,349kW (DXR)

Introduced due to the need for a more powerful locomotive on the North Island Main Trunk. DX 5362 was rebuilt as DXR 8007 in 1993, followed by DX 5235 into DXR 8022 in 2005. All DX locomotives now exist as DXB, DXC or DXR class locomotives. The DXB class is fitted with heavier drawgear, uprated engines, new cabs and BrightStar, while the DXC class additionally has lower air intakes for use in the Otira Tunnel.

DXB 5016

Tip: The DX class is much longer than the DC class, and the front hood is shorter as well.

TR class

Number range: 10-1026
Entered service: 1936
Power output: 78kW - 112kW (various versions)

A "catch-all" class, with many different manufacturers building various versions of the class. A handful remain in service for KiwiRail, including TR 56, their oldest locomotive. Several locomotives are preserved on private railways.

Diesel Multiple Units (DMUs)

ADL class

Trailer classification: ADC
Number range: 801-810 (ADL), 851-860 (ADC)
Entered service: 1982 (Perth), 1993 (Auckland)
Power output: 2x 205kW, one engine per bogie per motor carriage

Purchased along with the ADK class in 1993, intended to revive the Auckland rail network. The two classes were successful, and contributed to a rise in patronage from their introduction. The class was refurbished in 2002 in the new MAXX livery.

ADL 808

Tip: To tell the ADKs and ADLs apart, look at the bottom of the cab. The ADLs have yellow fibreglass attachments either side of the cowcatcher, while the ADKs don't. Also, the ADK's trailer unit, the ADB, only has one pair of doors on each side and is significantly shorter, while both the ADL and ADC have two pairs of doors each side.

Railcars

RM class - Silver Fern

Number range: 18, 24, 30
Entered service: 1972
Power output: 670kW

The Silver Fern railcars were introduced to bring back passengers due to road and air travel competition, then later replaced by the Overlander. The railcars were refurbished and are available for excursions. RM 24 is leased to the Taieri Gorge Railway, and RM 18 is stored out of service.
