Commonwealth Railways carbon steel carriage stock
In January 1963 Commonwealth Railways placed an order with Commonwealth Engineering, Granville for 24 air-conditioned carbon steel carriages.[1][2]
These standard gauge carriages were purchased for use on the Trans Australian between Port Pirie Junction and Kalgoorlie, as well as on The Ghan from Port Pirie Junction to Marree.[1]
At 22.92 metres (75 ft 2 in), they were the longest carriages in Australia. They were Commonwealth Railways' first Australian built standard gauge carriages, their predecessors having been manufactured in Europe or Japan.[1]
In July 1975, all were included in the transfer of Commonwealth Railways to Australian National. Some were converted to crew carriages for use on Trans-Australian Railway freight trains while others were sold to the Australian Rail Track Corporation.
