For one of BHP Whyalla's DE's in their last days before rebuilding or sale, I used Auscisions' T413 as a base with modifications including cab roof extensions, footplate reduction, new pilots and stairwells, exhaust silencer and airconditioner, new handrails and decaling and myriad smaller details. Two pictures here and also (for fun) a comparative of this model with other G8/G12 derivatives, and one fiction narrow gauge type (far left).
