Last fall I stated a critter using some early B’mann Porter parts and a Hartland mack hood.
I never did like it. So apart it came. Larry G Scale peddles a $15 Resin gen set on fleabay that’s a dead ringer for a Caterpillar D11000 (D6 or earlier Deisel 60) power unit.
As this mock up shows, the proportions are MUCH better. Is there a prototype? There were many steam switchers converted to Diesel mechanical over the years by various industrial shops… this one will be a Diesel Hydraulic, not common, but still quite possible
Re-arranging the cab configuration was a simple idea… getting the Welder contact glue joints to let go not so much.
Since the area under the engine is fairly open, I needed to think HOW a retrofit likely would have been mounted. I decided the most likely being the power unit skids just bolted to the original steam loco frame after the cylinder saddle was removed…
Out of time for now, more later.
