Point taken on the tender. They might retain a box car, more likely a small flat car for safety and easy "reach-ins". You can add a pick up there the wire can stay underneath.
It isn't an 0-4-0 necessarily either. I'm not 100% sure though as a hydraulic/chain mechanical makes me want to stick with Wyhte .. It is a "B" configuration traction engine I think (diesel electric and not an cabless A)
Similarly, I run a milk car, a second head end caboose (for easy reversing/run around), or mail car head end to let my GG-1 pull Broadway Limited cars on 0-27 without the GG-1 dragging cars wide (tight coupler knuckle in pockets =less swing; these cars have articulated coupler shafts & much better angles with the extra pivot.)
