The listings provided on these pages describe the locomotives currently owned and in operation with the various passenger and freight rail operators throughout Australia on the three main gauges. Most of the locomotives listed are operational on a regular basis. A small number are stored but are retained in the ownership of various operators. Some locomotives are stored temporarily and may return to service in the future. Others have been withdrawn from service and will eventually be scrapped. Stored locomotives are included because some will eventually return to service.
The locomotive class listings include locomotives operating on narrow (1067 mm), standard (1435 mm) and broad (1600 mm) gauge lines in Australia. Not included are many locomotives used on local industrial railways, such as those that service the sugar cane railway networks in Queensland. Also not included are steam, diesel and electric locomotives retained solely for historical purposes. Nevertheless, some units owned by preservation groups are hired at times to freight operators.
Some locomotives are not given a class designation by their operators, and in those cases they have been listed according to the model. Class names are sometimes used by more than one operator, such as the H Class and the P Class, but these refer to different locomotive types. Road numbers listed refer to those locomotives currently in existence. Original road numbers of the class may have included further units that have since been withdrawn. The same road numbers are sometimes used by more than one locomotive of different classes. The year of entry into service refers to the year the first member of the class officially entered service. In most cases the class leader, the member with the lowest road number, was the first to enter service.
Traction power figures refer to the traction output of the generator rather than the power of the diesel engine. Locomotive lengths typically refer to the length over the headstocks, which are the ends of the underframe of the locomotive. The headstocks support coupling equipment, which is not included in the lengths indicated.
The Locomotive Number Indexes page lists all locomotives described in number and alphabetical order.
