Okay, pilot printed, and it works perfectly. Except for not being able to fit the coupler through the hole where the coupler is supposed to go through. The back of the coupler will go through it, but in order to assemble it without completely removing the truck from the chassis (and I haven't yet figured out how to do that), either the knuckle of the coupler needs to be able to pass through the hole in the pilot, or there needs to be a hole in the pilot so the coupler can be attached, which might be seen as the pilot and truck swivel to negotiate curves.
So I'm faced with either opening the hole for the coupler up to unrealistic proportions to allow the standard Lionel non-scale coupler to fit, or to add a hole on top of the pilot so the coupler can be attached. Will experiment further tomorrow.
Have the chassis separated, and am currently working on fitting both ends into the shell. Have run into a clearance issue with the electronics, which should be able to be resolved by relocating them closer to the center of the engine.
