Many of the withdrawn 73 Class locomotives were purchased by sugar cane companies in Queensland. The units were purchased for rebuilding into 610mm units. Most of these units did not retain their original "short end hoods", and bear little resemblance to their predecessors. The main reveal is on the builders plate, which details the original number whilst in NSW government service.

Note: Some locomotives were not given numbers when rebuilt, just names - such is the nature of isolated sugar cane railways that numbers are not required for such a small fleet of locomotives. These locomotives are listed under their name, rather than a number. Numbered locomotives are listed as such, with the name in the locomotives listing.
