OK, my son and I want a steamer with a smoking whistle. We waited for the new Lionel catalog and our only choice was the Blue Comet. I was going to go with this then decided since I can't run the BC cars (O54) I would stay away from the Blue Comet (those cars may run on O48 but don't want the overhang). His second choice was the K4 from the 2011 Cataolg. Has anyone run these on Fastrack with an O48 curve?
