I'll throw in one bit of advice if you do go ahead with the 610-8057-200 smoke unit, which is a good smoke unit BTW, after a couple of mods. It comes with a 27 ohm resistor as standard, and this doesn't get hot enough to make diddely smoke. I suggest you change this out to a 20 ohm, 18 ohm, or even a 16 ohm MTH resistor. Second, if it has a woven fiberglass sleeve around the resistor, dump that with the resistor. Third, drill out the fan air intake hole to about 3/16" diameter or so. These mods allow the 8057 to make great smoke.
You want the smoke unit to add about 0.6 to 0.7 amps transformer load when switched on, using TMCC with 18 VAC track voltage. This equates to 11-13 watts power and will make lots of smoke from my experience.
