Beauty, power and performance all rolled into one! Here's the mightiest steam locomotive in the entire American Flyer roundhouse, a thundering behemoth made to 3/16-inch scale from blueprints of the Union Pacific Railroad's giant 4-8-4 "Northern" type. like the original, this American Flyer "smoker" is a dual-purpose locomotive, equally at home with along freight haul or at the head end of a string of passenger cars. Watch her pound along the rails, pistons flashing rhythmically, smoke streaming from the stock and choo-choo sounds keeping time with the big drivers. Here’s railroading as only American Flyer can produce it! From "cow-catcher" to rear coupler, this Union Pacific Locomotive and Tender is a mass of accurate detail; not a rivet head has been left out. Locomotive and Tender measure 21 1/2 inches. Includes Smoke Capsule and Funnel plus complete Instructions.
