MTH Smoke on Conventional AC

Is the smoke switch on or the smoke regulator turned up? In conventional the switch controls smoke.  G

9 volts on the track isn't near enough voltage/current to heat the element in the smoke unit, in order to produce lots of smoke.

So I'll turn the "smoke volume" all the way up and see what happens.  At 9 volts it has good speed.

Good idea. However, at 9 volts are you pulling many cars in order to obtain "good speed"?

6 or 7 cars.  I'm measuring voltage via a multi-meter while the train is running.

Our experience through testing on our layout, is that with M.T.H. smoke units, they really don't come alive until 14-16 volts. That is required to heat up the smoke unit element and vaporize the smoke fluid and produce a lot of smoke. They will smoke at lower voltage, but it will be noticeably weak compared to the higher settings. With customers who operate in conventional mode, we always suggest adding to the consist by at least 2 cars which will require turning up the voltage. The end result is more smoke. Hope this information is helpful.
