smoking caboose err upgrade

I am upgrading a 19807 smoking caboose to command control using a err mini commander for accessories. The smoke unit (10-2722-50) has a 1 ohm 10 watt resistor connected in series with it. I can only assume lionel added the resistor to limit voltage to the smoke unit. Can I remove the resistor and connect the smoke unit directly to one of the high current outputs on the mini commander? And if so, what would be the recommended voltage? I cannot find what the specs are for this smoke unit.

Thanks

That's a good way to overheat your smoke unit and melt your caboose. Myself I wouldn't do it. There's a post somewhere that Gun runner John explains how to use a MTH HO fan driven smoke unit that can be installed in smoking caboose's to get more smoke output.

One thing about trains, it doesn't matter where they are going, it's having the sense to get on.

Truthfully, if you like a smoking caboose, consider putting something like the MTH HO fan driven smoke unit in the caboose.  The element likes around 5V, and the fan will run on 2-3 volts DC.  It gives you nice smoke for a caboose, and won't overheat the sides of your caboose.

How am I overheating the smoke unit? I can configure the mini commander to put out any voltage from 2 to 18 volts.

Since you can control the voltage, I forgot about that, as long as you don't put to much voltage to the unit you won't. I think John's solution is the way to go.

GRJ, what does the MTH HO smoke unit usually cost?

Around $40 MSRP if I remember correctly.  I still have a couple, so I haven't bought one in a while.

What was the purpose of the 10 watt resistor in the original setup?

Obviously for current limiting, but I'm not sure why.
