Thanks Bill! 

Hello all!  I have recently come into possession of a North Pole and Southern #12 engine and tender.  I love it!  It runs great and the sound is amazing!  I did, however, think that it was a smoker and I can't figure out if it is or not.  So my question is if anyone knows if it is a smoker and, if not, is there a way to convert it?  Thanks in advance for tips and answers!

rich1998 and Len thanks for the info!

Hello all!  I just came into possession of a Bachmann North Pole and Southern #12 engine and tender.  I love it!  Only thing is that I thought it was a smoker and it doesn't seem to be.  I am "new again" to the g scale hobby and am just wondering if anyone can tell me how I can know for sure if it's a smoker and, if it's not, if it can be converted.
Thanks in advance for any tips and info you can provide!
