I was looking for information on the HO Scale Tangara, and this crossed my path. PowerHouse Museum
They claim something about it being a Comeng Design from 1970-1980
From the Website "
Model, Tangara Sydney suburban railway carriages, (2), control trailer carriage and motor carriage, timber / metal, designed by John Dunn, senior concept designer, Comeng, Granville, NSW, 1970-1980
Statement of significance
These two large timber models are representations of the double-deck Tangara EMU (electric multiple unit) Sydney suburban railway control trailer and motor carriages. They were the work of John Dunn, senior concept designer of Comeng, Granville, New South Wales, between 1970 and 1980. The full-size versions of these EMUs began operation on the Sydney CityRail suburban rail network in 1988.
As John Dunn said in his 2002 paper "Double-deck power cars expand EMU capacity", Sydney led the way in 1964 when the New South Wales Government Railways (NSWGR) introduced 20m-long double-deck trailing cars to its fleet of single-deck units serving Sydney's 1.5 kV DC suburban network. This increased the carriage seating capacity by 47 percent. Entry was by stairs from large vestibules at opposite ends of the carriage. (The design was based on carriages developed in Paris in the 1930s). Double-deck power cars, which needed to squeeze in power and air-conditioning equipment into a smaller roof compartment space, came later and required creative thinking from designers and equipment suppliers. In 1970 New South Wales was the first in the world to develop traction and air-conditioning modules in the roof of double-deck interurban trains. However, in many European countries including France, Germany and the Czech Republic, the adoption of double-deck EMUs did not take place until the 1980s and 1990s. Now (in 2012) as more people turn to public transport in car-choked urban environments many more countries are looking to increase the carrying capacity of their single-deck railway cars as Sydney did.
The Tangara (the word is aboriginal for "to go") cars are now the third generation trains on the Sydney electric network after the Bradfield single-deck "red rattlers" and double-deck silver cars. Although the Tangara design did not increase the number of seats it did provide larger vestibules and wider stairways for access to both decks. This decreased passenger loading and unloading times.
These models are known as styling models and were produced to show how the train would look to New South Wales State Rail Authority executives.
The Tangara has been acknowledged as an important double-deck electric multiple unit design. At the time, the 450 Tangara car contract was the largest ever let in Australia for railway rolling stock. They were all made by the Australian engineering firm, A. Goninan & Co.
