Modification for the Polar Express

[Sumpter250]

Yup!, the added weight increases the amperage drawn, so there is more heat to create smoke -------"howsomever",,,,
That same excess current also flows through the motor windings ( so there is more heat to create smoke )...and it does create more smoke! from the smoke unit......and from the motor !!

8-) oooh, and maybe also from the dried out "tree".... 8-) 8-)

All kidding aside, I would tend to advise the use of an aftermarket smoke unit to produce more smoke, rather than upping the current in the locomotive.
