Hi there, complete neophyte here looking to get back into the hobby. 

I love the steam locomotives, but I'm reluctant to buy one with a smoke unit for safety/cleanliness issues.  Anyone have any recommendations for a steam locomotive with no smoke unit or at least a switch to turn it off? 

I liked the festive color of the Bachmann 50402 HO Smoky Mountain USRA 0-6-0 Steam Locomotive w/Tender #99 or USRA 0-6-0 w/ Smoke & Slope Tender - North Pole & Southern® #25. 

Any guidance is appreciated!
