If this is older TMCC the answer is no. If you turn the smoke switch off does it stop the smoke unit? Your unit does not have the ACREG based on Lionel parts list. So it sounds like the R2LC Triac is shorted, or the engine has been rewired to power the smoke unit from the track.

The smoke unit should have power coming from the mother board smoke output go to the switch, and from the switch to the smoke unit.

If wired correctly I would swap the R2LC to see if that is the problem. If so, the Triac can be replaced. G
