Hey guys, a quick question, just purchased a Jingle Bell  Express for under the Christmas tree this year. The parts breakdown sheet that came with the set indicates a USRA 0-6-0 locomotive "with smoke" ..and shows the smoke unit #2951. There is no advertising on the box that this is a smoke producing locomotive and there was no smoke liquid included with the set. So my question is ... is this really a smoke producing locomotive or did i just get the wrong parts breakdown sheet in the set.  Thanks for any help....Mark
