Right out of the sealed box, although my Lionel Century Club PRR S-2 Turbine runs like a swiss watch..unfortunately, as soon as I apply power to the track, even before the S-2 Turbine starts, I hear what sounds like a smoke unit whirring.
Then, when I start up the engine and run it, I do not see smoke issuing from its smoke stack...instead it is coming out of the bottom and sides.
Looks really cool, especially the way it settles like a fog between the rails, but I do not believe it is supposed to do that.
It also keeps oozing smoke, for about 30 seconds and then slowly disapates after powering off the engine and track.
