Tough Crowd. What other train manufacturer/importer is adding features like this to their locomotives?
I'd be interested to see what you would come up with as features that are not already on this locomotive. If not the coal load, then what? Not being argumentative, but what feature would you make.
A waving engineer? A non prototypical swinging bell? Exploding boiler?
Seriously though throw some ideas out. Maybe one will get traction.
