The New Zealand DB class and DBR class [nb 1] locomotive is a type of diesel-electric locomotive built for service on New Zealand's rail network. They were built by General Motors Diesel (GMD) of Canada as a narrow-gauge version of the EMD G8 model, with seventeen locomotives constructed. Ten of these were later rebuilt into the DBR class.
The DB class was introduced to the rail network in 1965-1966 as a result of a requirement for a modern locomotive that could operate on the North Island lines that the DA class was excluded from due to their weight and axle load. [1] [2] They were ordered at the same time as the final DA order was placed. [3] [4] While these were mainly branch lines, it also applied to the East Coast Main Trunk line, particularly the section beyond Paeroa through the Karangahake and Athenree gorges until the opening of the Kaimai Tunnel on 12 September 1978. [5]
The class was virtually indistinguishable externally from the DA class, being of the same basic design and dimensions, and wearing the same livery. They were some 13 tonnes lighter with a V8 prime mover as opposed to a V12 in the DA class, though the classes shared the same A1A-A1A wheel configuration and traction motors for commonality. The locomotives were supplied with cast-steel bogies manufactured by Dofasco, but these were swapped with phase I DA class locomotives, which were delivered with fabricated bogies, once the DB class entered service. [4]
The class was initially numbered DB 1000 to DB 1016, this being in common with NZR practice of the time to number locomotive classes with reference to the power output.
Upon the introduction of the computerised Traffic Monitoring System (TMS) in 1979 the class was renumbered and the designation capitalised. The class received new four-digit numbers beginning with 1, in which the last number is a check digit for the whole number. Under the new system, DB 1001 retained its number, becoming DB1001, with DB 1000 becoming DB1018. The rest of the class was renumbered in sequence, with DB 1016 becoming DB1180.
The units being rebuilt to DBR received a new TMS number in the 12XX range when they entered the rebuilding cycle.
In the late 1970s the decision was made to rebuild the DB class along similar lines to that being undertaken for the DA class into the DC class. [5] The rebuilt DB units were designated as DBR (R = rebuild). The rebuilds were done by Clyde Engineering in Australia and involved the lowering of the short hood to improve visibility for the driver, new cabs similar to the DC class, and the installation of a new EMD 8-645 engine. Ten units were rebuilt between 1980 and 1982. [6] [7]
The DB class was employed primarily freight duties, though they did also see occasional service hauling passenger trains. As lines and bridges were upgraded, and in the case of the ECMT the Kaimai Tunnel opening, the weight advantage the locomotives had over other classes used in the North Island became less of a factor and the locomotives were operated as part of a general pool.
Initially, all DBR class locomotives were allocated to the North Island. [8] The lightweight nature of the DBR locomotives meant they were well suited to operate some South Island lines following the withdrawal of the DI and DJ class locomotives in the early 1990s. [6] The last DBR returned north from the South Island around 2007. [9]
From 2003 [10] to 2014 two locomotives were leased to the Auckland Regional Transport Authority and then its successor, Auckland Transport, with the services operated under contract by Transdev. The two locomotives, DBRs 1199 and 1254 are operated in a top and tail configuration with the five car SX carriages set and wore the full MAXX Blue livery. A third unit, DBR 1226, was also painted in MAXX Blue but without the MAXX logo. DBR 1226 was usually used for freight services or work trains by KiwiRail but was used as back up for DBR 1199 or DBR 1254 as it had the necessary modifications to work with the suburban carriages. The leases expired in 2014 and the locomotives returned to freight service. [11]
For many years two DBR class locomotives formed the basis of a banker set out of Wellington, primarily assisting trains between Wellington and Paekakariki but also performing multiple other jobs including the Hutt Workshops shunt, work trains around the region and any unusual movements. DBRs 1199 and 1200 were the initial pair, becoming known as the "Bobsy Twins" (sp), likely a reference to the Bobbsey Twins due mainly to their consecutive numbers (a rarity under the TMS numbering system). In the early 2000s DBR1199 suffered a failure and was withdrawn from service and laid up, replaced on the banker set by DBR1267. DBR1199 was later sent to Hillside for repair and use on the Auckland SX set commuter trains, by which time the pairing of DBRs 1200 and 1267 had become known simply as "The Twins". DBR1267 was later transferred to Auckland to replace DBR1282, [12] with the Wellington banking role taken over by other locomotives.
The locomotives were delivered in the same overall deep red livery as the DA class, with the same white stripes along the sides and "wings" on the ends. With the introduction of TMS the locomotives road numbers were applied in large white numbers to the long hoods.
This livery was worn by many of the original DBs until their retirement, while the DBRs were returned to service in the International Orange or "Fruit Salad" scheme (red and grey with yellow safety ends) being applied to most NZR locomotive classes at the time. DBs 1082 and 1099 also received this livery in the 1980s.
DBR 1295 was repainted into the Toll Rail "Corn Cob" scheme (yellow and green), and the three units used on Auckland services have received the MAXX Blue livery (deep blue and yellow). More recently DBR 1267 has received the KiwiRail grey, red and yellow scheme.
As of May 2017, all units have been withdrawn from service. The locomotives were withdrawn on account of being either surplus to requirements, or in poor mechanical condition. All of the DB locomotives were withdrawn by February 1989. In the early 2000s, DBRs 1199, 1239 and 1241 were withdrawn and placed into storage at Hutt Workshops. [13] [14] DBR1199 was reinstated a year later for suburban trains in Auckland, [10] [15] and 1239 and 1241 were scrapped at Hutt Workshops in February 2008. [16]
More withdrawals commenced in July 2013, with 1200 being the first. [17] [18] A few more were laid-up over the next few months. [19] [20] In February 2014, 1267, 1282 and 1295 were reinstated due to the DL class locomotives being taken out of service after samples from one locomotive tested positive for asbestos. [20] [21] Withdrawals began again in May of that year when 1282 was laid up. [21] [17] The rest have been withdrawn, with 1226 being the last. [22]
In June 2017, KiwiRail issued a Request for Quotation (RFQ) via the Government Electronic Tendering Service (GETS). [23] [22] In August 2017, it was announced that DBRs 1254 and 1295 have been purchased by the Glenbrook Vintage Railway. [24] [25] The remaining DBRs were originally sold to a locomotive/rolling stock dealer in South Africa, [25] but have now been sold to DBM Contracting. [24] [26]

In August 2017, it was announced by the Glenbrook Vintage Railway that they had purchased DBRs 1254 and 1295 for eventually hauling mainline excursions. [24] [25] After being stored at Hutt Workshops, the pair arrived on-site on 3 November 2017. [26] In March 2018, 1295 was repainted in the "International Orange" livery. [27] [28] In May 2018, work started on overhauling 1254 for mainline certification. Both have been given GVR numbers, which are No.11 and No.12 respectively. [29] DBR 1254's restoration was completed in September 2019, and is now mainline certified. [30]
The DQ and QR class were a class of diesel locomotives in New Zealand and Tasmania, Australia. Originally built by Clyde Engineering in the 1960s as Queensland Rail 1460 and 1502 class locomotives, they were purchased by Tranz Rail in 1995 to be rebuilt, as a cheaper alternative to buying new locomotives.
The New Zealand DI class locomotive was a class of diesel-electric locomotive in New Zealand. They were built by English Electric at their plant in Rocklea, Queensland in Australia. The class is very similar to the Queensland Railways 1620 class locomotives. At the time of their introduction, the class was seen as an alternative to the DB class for use on lightly laid secondary and branch lines, more so in the South Island. The World Bank financed introduction of the Japanese built DJ class in 1968, which ensured that no further DI class locomotives were purchased by New Zealand Railways.
The Glenbrook Vintage Railway (GVR) is a heritage steam railway in Glenbrook, New Zealand.
Bumble-Bee was an informal term, promoted by the editors of NZ Railfan magazine, describing a New Zealand railway locomotive livery found in common usage amongst the railfan community.
The New Zealand DC class locomotive is a type of diesel-electric mainline locomotive on the New Zealand rail network, operated by KiwiRail on freight trains, and formerly on long-distance passenger trains. The class was rebuilt from the DA class in the late 1970s and early 1980s, mainly in Australia. After the DA class, they were the most numerous class of diesel locomotive on New Zealand's railway network and remained numerically dominant until the mid-2010s when withdrawals began.
The New Zealand DX class locomotive is a type of diesel-electric locomotive that currently operates on New Zealand's national railway network. There are 49 of the locomotives and all are owned by KiwiRail. They have a Co-Co wheel arrangement.
The New Zealand DA class locomotive is a class of diesel-electric mainline locomotives operated on the New Zealand railway system between 1955 and 1989. Consisting of 146 locomotives, it is the most numerous class to ever operate in New Zealand, with five more than the AB class steam locomotive.
The New Zealand DE class was a class of fifteen diesel-electric shunting locomotives, introduced by the New Zealand Railways (NZR) with an intention to replace steam locomotives on shunting duties with diesel power. The class was physically similar to the Tasmanian Government Railways X class, which was also of English Electric design.
The New Zealand DF class locomotive of 1979 is a class of 30 Co-Co diesel-electric locomotives built by General Motors Diesel of Canada between 1979 and 1981. Between 1992 and 1997, all the locomotives were rebuilt as the DFT class, a turbocharged version of the DF.
The NZR RM class Standard railcars were a class of railcar operated by the New Zealand Railways Department (NZR) in the North Island of New Zealand. Officially classified as RM like all other railcar classes in New Zealand, they acquired the designation of "Standard" to differentiate them from other railcar classes. They were introduced in 1938 and withdrawn in 1972.
The New Zealand DSC class locomotive is a heavy shunting locomotive used throughout New Zealand. The class was built in seven batches, the first 18 locomotives being built by British Thomson-Houston of the United Kingdom, with the further 52 locomotives being built by New Zealand Railways (NZR).
The New Zealand TR class locomotive is a type of diesel shunting locomotives built by many different manufacturers. Defined as "shunting tractors" or "rail tractors" by KiwiRail and its predecessors, they are classified "TR" for tractor as a result. Many of these locomotives have been withdrawn, but some are still in service. The first locomotive of this class was built by NZR in 1924. The most powerful were Japanese-built Hitachi TRs, with 138 kW Cummins engines.
Steam Incorporated, often abbreviated to Steam Inc., is a railway heritage and preservation society based at the Paekākāriki railway station, Paekākāriki at the southern end of the Kāpiti Coast, approximately 50 minutes north of Wellington on the west coast of New Zealand's North Island. Unlike some societies who operate on preserved sections of closed branch lines, Steam Incorporated owns a depot beside one of the country's most important railway lines, the North Island Main Trunk railway, and restores heritage locomotives and rolling stock for use on excursions on the regular national rail network.
The New Zealand EA class of electric locomotives were used on the New Zealand rail network between 1968 and 1997 on the Otira – Arthur's Pass section of the Midland line in the South Island, through the Otira Tunnel. Following reconditioning, three were used by KiwiRail's Tranz Metro in Wellington from 2008 to 2011 to top and tail Metlink suburban passenger trains as an interim measure before new rolling stock arrived. Four of the five locomotives were scrapped in 2013 with one being set aside for preservation.
The New Zealand British Rail Mark 2 carriages were built by British Rail Engineering Limited for British Rail in the early 1970s. From the mid-1990s, 150 were exported to New Zealand. After being rebuilt, refurbished and re-gauged, they entered service with a variety of operators on New Zealand's railway network. The carriages generally replaced older NZR 56-foot carriages, some of which had been in use for almost 70 years.
The NZR DSB class locomotive is a type of shunting locomotive introduced to New Zealand's national rail network in 1954 by New Zealand Railways (NZR).
Cato Blue is an informal term describing a New Zealand railway locomotive livery found in common usage amongst the railfan community. The livery was first worn on DFT 7160 as a variation of the New Zealand Rail blue livery. With the introduced of Tranz Rail on 18 October 1995, the livery was adopted to replace New Zealand Rails blue livery, which was introduced in 1991. The scheme was known as Cato Blue after its creator, Cato Partners. DFT 7199 was the first locomotive repainted in the livery after Tranz Rail took over the rail system.
Corn-Cob was an informal term, promoted by the editors of NZ Railfan magazine, describing a New Zealand railway locomotive livery found in common usage amongst the railfan community. The livery was introduced on 5 May 2004 when Toll Rail took over the rail system from Tranz Rail and replaced the Bumble-Bee livery. The livery was replaced by the KiwiRail Phase One livery in July 2008. DX 5379 was the first locomotive to wear the livery. The livery represents the colours of Toll Rail and the colours of Australia. When KiwiRail took over the rail system from Toll, the Toll logos on the locomotives were covered or "patched" with the KiwiRail logo.
The DQ class were a class of diesel locomotives in New Zealand and Tasmania. Originally built by Clyde Engineering in the 1960s as Queensland Rails 1460 and 1502 class locomotives. They were purchased by Tranz Rail in 1995 to be rebuilt, as a cheaper alternative to buying new locomotives. Tranz Rail rebuilt 16 locos into the DQ class. Tranz Rail then sold the 12 DQs to AN Tasrail. Only eight out of the twelve DQs are still in service today.
The QR class were a class of diesel locomotives in New Zealand and Tasmania. Originally built by Clyde Engineering between 1965 and 1966 as Queensland Rail's 1460 class locomotives. They were purchased by Tranz Rail in 1995 to be rebuilt, as a cheaper alternative to buying new locomotives. Seven were modified into the QR class. Three were leased to AN Tasrail for one year, but the locos were later sold in 2001. All three have since been scrapped.
