Atlas O gauge Burlington F3 diesel
Unfortunately I own the F3 series prior to this one. No smoke. From your description the coil coupler is in front? A dummy coupler is in the rear at least on mine. If Atlas made any revisions, they should have placed the operating coupler in the rear, where it belongs. They certainly run smoothly with Legacy though. If only Jim Weaver were alive, Atlas would have gotten it right.
