@Rod Stewart posted:OK I get it now; did not realize the whole smoke unit sits lower in the engine. Cool. That video shows it all off nicely; looks like a huge improvement! Hope you had your train room exhaust fan running!!
It was putting out some good smoke, I can still smell a whiff of it today down here.
@Rod Stewart posted:Lowering the smoke unit might not be an option in some engines where the fan motor is already really close to the frame plate. The LM Challenger is a good example.
Possibly true, the LM stuff is quite different inside than the scale locomotives. I'm going to be upgrading a scale Challenger soon, I'll have to see what a stack improvement looks like for that one.
