A summary of published research


The history of the locomotives used by the New Zealand Government Railways (NZR) is both intriguing and complex, particularly during the early years. This is brought out in several published works which attempt to unravel the complexities of early numbering and classification systems. This page and its sub-pages are intended intended to be able to be expanded to capture any level of detail desired about New Zealand railway locomotives.

The very early railway development in New Zealand was authorised by the Provincial Councils of the time, and all independent of each other, so any numbering of locomotives was also without any consideration of how things might develop in the future. It was also a period when locomotives tended to get allocated names, with some some rules around what types of locomotives received what type of name. By the time the Provincial Governments were abolished in 1876, a structure for a national railway network was already taking shape but it was not until two years later when the Railways Department and the Public Works Department were separated as two separate entities, the Railway Department in charge of running trains and the Public Works Department in charge of building railway lines (among other things), that serious thought was given to how such things as a national locomotive numbering system could be established. Given the haphazard start to railways in New Zealand, and the time that has elapsed since then, it is little wonder that understanding all the steps along the way could become a challenging task, one that was ultimately taken up by a number of different researchers.

The earliest formal publication devoted to NZR locomotives was curiously published in the U.S.A., the work of Tom McGavin, summarising the results of the work of several NZR&LS members. An address was given to Society members by Tom in 1950 and a duplicated transcript of the talk made available. An expanded version of that, with illustrations, was then published by the Railway & Locomotive Historical Society in their "Bulletin 81" in the U.S.A. The work was titled ["The Steam Locomotives of New Zealand Government Railways 1872 - 1949"]. From this came the first New Zealand publication, "Steam Locomotives of New Zealand Since 1863" (1st edition 1950) with a second revised and enlarged edition in 1961. A complete update of the material covered by these early publications resulted in a set of three new volumes, Part one by T.A. McGavin dealing with 1863 - 1900, the other two by E.J. McClare, Part two dealing with 1900 - 1930 and Part three 1930 - 1971. These booklets still provide a very handy ready reference of the various steam locomotive types used throughout NZR's history.

The first attempt to document all the steam locomotives used on New Zealand railways was carried out by Bill LLoyd, and presented in a publication "NZR Steam Locomotive Lists 1880 - 1957". This was issued by the Railway and Locomotive Society as Supplement No.5 to their quarterly publication "The New Zealand Railway Observer". This first list was however not a complete story as it used the 1880 locomotive list (issued as an appendix to the Journals of the House of Representatives) as a starting point, with no attempt to unravel and reconcile any earlier numbering systems. A further 10 years of research resulted in the publication of the first formal attempt to provide a complete register. The "Register of New Zealand Railways Steam Locomotives, published in 1974. 27 years later after much further research, an enlarged and revised edition was published in 2002. Both these edition are serious reference works, listing every locomotive of every class that worked on Government railway lines.

At the time of the centenary of New Zealand railways in 1963, a new work was published as a historical record of all classes of locomotives used by the New Zealand Government Railways, including Steam, Electric and Diesel. This was a collaborative effort by A. N. Palmer and W. W. Stewart and was titled "Cavalcade of New Zealand Locomotives" this is still a very useful reference, outlining all the locomotive types from 1863 to 1955 for the 1st edition, and to 1965 for the 2nd edition with a convenient Locomotive index and list of builders at the back.

During the early 1960's, Peter Dyer was busy compiling data on the Public Works Department steam locomotives, a more challenging task given the dearth of early records that existed. He subsequently published a booklet in 1966 titled "Steam Locomotives of the New Zealand Public Works Department".

A separate branch of locomotive research was carried out by Gerald Petrie, looking at steam locomotives in New Zealand other than those operated by NZR. This resulted in the publication of "New Zealand Steam Locomotives by Official Number" in 1993. This was followed 3 years later by "In the Beginning", a detailed look at all locomotive data between 1863 and 1877 in an attempt to unravel most of the mysteries that surrounded certain old locomotives. Then in 2007 a detailed analysis of all available data relating to the early numbering of New Zealand Railways locomotives "Locomotive Numbering from 1890 back to 1863 - The Evidence". This is a fully documented research effort with scanned copies of all early documents found to support the conclusions reached.

The focus of the above publications have all been on steam locomotives, however, soon after Tom McGavin's first publications he started producing what became a series of booklets reviewing the motive power that was in use oby NZR in 2002 David Parsons published a book titled New Zealand Motive Power 2002 that reviewed each class of locomotive in use at that time. This was followed up with an updated version in 2018, so together with the other books, a complete record of railway motive power in New Zealand now exists.

In 2011, Sean Miller published a completely up to date work titled "The NZR Steam Locomotive". This fine reference work covers each locomotive type, including a short section on unclassified locos, steam railcars etc. It has many fine illustrations but lacks some details you would expect to be able to find in such a well presented publications.

Locomotive Classification

The study of locomotive classification attempts to come to an understanding of why particular locomotive groups received the classification letters they ended up with, and why particular numbers were allocated to particular locomotives, perhaps not so important to the general rail-fan, but a fascinating conundrum to the serious researcher. Sean Millar made this his particular challenge and in 2001 he published a slightly controversial book titled "From A to Y excluding I", which was a first attempt at researching locomotive classification and included a fair bit of speculation where no hard evidence could be sourced, and yet a conclusion wanted to be reached. This was followed in 2018 by a new work, "Classifying New Zealand's Locomotives" being a more serious look at the classification issue and includes the diesel and electric locomotives.

There is of course much more published material available, particularly articles in periodicals like the Observer and Railfan, however these tend to look at individual locomotive classes rather than the collection as a whole. it is hoped that descriptions of these articles too will eventually be included in this wiki to help researchers locate all relevant material.

Locomotive Types

A locomotive's wheel arrangement can be described in a number of different ways, for steam locomotives, the system commonly used in New Zealand is known at the Whyte System where a sequence of numbers, separated by dashes, denotes the wheel arrangement e.g. 4-6-2. Appended to this code can be a series of letters to signify that it is a particular kind of tank locomotive e.g. 0-4-2ST. Apart from the number/letter code, some steam locomotives also had names for the particular type of wheel arrangement e.g. 4-6-2 was also known as a 'Pacific'. There is a second system used primarily in Europe so known as the Continental System and caters for steam, diesel and electric locomotives within the one system. Here in New Zealand we use that system for defining our diesel and electric locomotives, so we need to understand two systems to be able to record the wheel arrangement of any locomotive in New Zealand.
