Antonio,
There are two main groups of these still running;
Double end units, with a bulldog nose on each end - model AA16C (called ML2 at first)
There were 26 of these numbered B60 to B85, all with the Victorian Railways, 5’3" gauge.
B61, B65 and B80 were all working for West Coast Railway, basically a commuter line running south west of Melbourne. B61 works the commuter trains, B65 is leased to Freight Australia for grain traffic, B80 is painted in a version of UP colours for a tourist service that never started, and was on standard gauge freight service until some contactors failed. It is expected to be back in service soon.
There is also B74, with a museum at Seymour, north of Melbourne. It spends a lot of time in Freight service on lease, but is in its original EMD blue and yellow, like a cross between Erie and Santa Fe Freight schemes.
Eleven units were rebuilt as AAT-22CR (a sort of SD39-2 in a double end cab body), six now work commuter trains (in red and blue) and five work broad gauge freight, in green and yellow.
There were a lot more single end units, but not as large a proportion survive,(although there are quite a few still about.
There were 11 single end A1A-A1A units, Commonwealth Railways GM1 to GM11. these were 1500HP with 16-567B engines (like the double end units).
GM1 and GM3 are restored to original appearance in maroon and silver, looking like the purple ACL scheme. (The maroon was known locally as “German Purple” fom some German built streamlined trains that ran with them). GM1 is with ARG, and is looked after well, and only used when badly needed. GM3 is with the EMD licensee, EDI Rail at Bathurst. GM10 is owned by Chicago Freight Car, and is in lease service. It is lettered Great Northern, but painted in GM&O maroon and red.
GM12 to GM47 were 16-567C units , 1750 or 1800 HP, and were driven on all axles. They had four portholes each side, which made them look m
