The idea of Australian rolling stock with American locos sounds good to me. Modified of Corse, to make a hybrid loco. I have 2 roundhouse 4-4-0’s an old IHC 4-6-2,4-6-4,0-8-0… Add some buffers, get rid of the cowcatchers, add a belepair firebox, some shunters steps and give it all a repaint and I’ll have some nice aussie locos.B)
