Remarks: 2100 was born as QR 2358 in 1973, 2350 English Electric hp. When QR decided to purge the EEs from the roster, Aussie National acquired many and dispatched them to Tasmania from 1987. This locos identity then became ZB9. After fire damage, ZB9 was sent to Port Augusta in 1996 and rebashed with a shovel nose. It then became briefly ZR1, to be renamed as ZP1. Then when Ed of the WC took over, the identity changed to 2100. Tasrail have derated the ZB units and 2100 to 1800 hp. 2100 is also dual control voltage to permit multiple working with EMDs.
