You did add more drops of smoke fluid right?
I mention this because a newbie did not read the instructions ! He ran the smoke unit with out adding more smoke fluid ! hence the smoke unit was destroyed !
He had the nerve to blame the dealer ! Dumb choice ! I was there when he bought the train & when he brought it back saying the smoke unit did not work! The dealer told him to add 8 to 10 drops at unpacking the train ! or turn off the smoke unit !
Add 5 drops to smoke unit as the smoke volume decreased if running the smoke unit !
The dealer won ! that battle because I was there to back up the dealer ! The guy had to send in engine to lionel ! I don't if he did !
