G class

The G class were introduced under V/line in 1984. First Series G classes were an extention of Australian National's BL class order and are the same in pretty much every way. Some have been rebuilt with EMD 16-645F3B engines (G523, 526, 529, 530, 531, 536, 541, and 543) with the old ones going to XR rebuilds. Rebuilt G's would have the model designation JT36C-2SS. G541 has been refitted with an EMD 16-645E3C engine after the F3B engine failed.
