At the time Comeng produced this book to showcase its products Comeng was the Rolling Stock Division of the ANI Corporation. There had been a time when Comeng was an independent company but by the early 1980s Comeng had been absorbed into ANI and it would only be a few more years before Comeng would bow out of the railway business all together.
However when this book was produced Comeng was still a mover and shaker in the railway manufacturing scene in Australia. Comeng maintained plants in Sydney and Mittagong in New South Wales, Western Australia, Victoria, South Australia and Queensland.
Comeng equipment was in use in most states of Australia and its catalogue contained a wide variety of rolling stock and other railway equipment. Even today Comeng equipment is in continual use throughout Australia..
