I am interested in the conventional road vehicles employed by Commonwealth Railways, Australian National Railways, and Australian National in the period 1950 to 1985 approx (not to be confused with hyrail or section cars). The vehicles in question would have been assigned to fettler gangs, inspectors, and administrative staff.
Any details, no matter how limited, including vehicle makes, colours, dates, registration numbers, and/or photographs would be terrific. Presumably, all carried white "C of A" plates with a "Z" prefix. So far I have identified the following vehicle types from black and white and colour images: -
Austin Lodestar truck, maroon cab?, c. 1950;
Austin WD truck, dark teal blue cab, c. 1962;
Land Rover ute, S.W.B., grey, c. 1963;
International Acco truck, white cab, c. 1983.
