Comeng is an abbreviation of "Commonwealth Engineering", and was a division of ANI. In the late 80's / early 90's, Comeng was taken over by ABB. Then, more recently, ABB merged with Daimler to become ADTranz. It is now part of Bombardier Transportation.
As well as work in conjunction with Alco, and subcontracting with Clyde, Comeng has also built diesel and electric locomotives with equipment from other suppliers.
On its own, Comeng has built around 145 electric and some 60 diesel locomotives for Australian operators, many of the latter being smaller shunting and industrial types.
Comeng have had factories in Dandenong (Melbourne), Rocklea (Brisbane), and Bassendean (Perth). Only the Dandenong factory is still around; it is now used by Bombardier.
The list below only covers those locos on Locopage; the units for sugar cane tramways and other industrial units are not listed. You will need to download the spreadsheet (on the Builders Numbers page) for that.
