What does the unit look like? What is it made of? How long a run did you get?

No chuffing I see..

That's what it looks when its working (close to burnup voltage (12volt!!)
I was impressed by the video; and intended to buy that type of smoke unit. But at first, I want to test the smoke unit of the NW2-USA trains locomotives, and I was disappointed by how much the smoke unit actually takes up power. Usually, for that NW2 locomotive; it runs several hours on a full battery. This morning, the locomotive was fully charged and with the smoke unit turned on, it could run less than 15 minutes. Anyone has experience with the USA trains-NW2 smoke unit, please share your experience. I am afraid the Habor Models smoke unit will do the same.

OK,

So the early USAT smoke units take about 1/2 amp, heater only, no fan, etc:



Or do you have the later fan driven ones?


The first one takes under 1/2 amp, the second can take almost one amp.

BUT!!!

The Harbor Models ones can take 2 amps.... no offense, but did you read their site and the specifications?

If you are running battery, you will be one of the few that uses smoke... You can use MORE power for the smoke unit than the motor.

You cannot get something for nothing in this world, and boiling lamp oil takes power.

Thanks Greg for the information.
I did open up the USA train NW2 when I modified it for battery powered; but I didn't notice what type of smoke unit they used. But I am certain that there is no fan since the smoke is very little not the kind blowing up profusely by the fan. If the Harbor Models uses 2amps, it is nearly impossible for battery powered locomotives. My ion lithium battery has only less than 4 amps.

Yep, it really uses a lot of power.... now, stock the fan powered USAT units will take under an amp, but if you use them in "direct mode" from a DCC decoder, for example, you can use about 1 amp for the heater and 1/2 amp for the fan.

Stock, the USAT fan type units run a lot less aggressively, and make less smoke... so the smoke volume is not always the conclusive way to determine what model you have.

I have not opened my NW-2's to look inside at what they came with.

As my pal discovered. I went round to see his Mallet run with its new Harbor Models smoke unit, and the batteries died after 1/2 hr [although I think he'd been running it before I turned up, so the run time is suspect.] He was surprised.

The unit can actually use over one amp...

The specs are right there on the web page:

Dimensions: 2-1/8" L (2-7/8" with mounting tabs) x 1-1/2" W x 1-1/2" H
Weight: 1.4oz. when filled with fluid
Run time: ~3-1/2 hours on 1/2oz. of fluid
Draw: ~1.2 amps at full throttle Voltage: 6 Volt



So, I'd be interested if he used the small unit and had 6 volts..

Anyway, it will eat a battery faster than the motor as you can see from the specs.
