The product is a vintage Märklin Gauge 1 Clockwork Locomotive from 1910, featuring a cog, rack, and climber design. Made of cast iron and tin, this locomotive was manufactured in Germany. This classic piece of model railroad equipment is a collectible item for hobbyists and enthusiasts of vintage model trains. The intricate design and historical significance make it a valuable addition to any collection of model railroads and trains. The engine does climb and works in both foreword in reverse as seen in the videos. I am not an expert on these. It includes 8 pieces of track. To be shipped in two separate boxes and insured. Shipping cost reflects this. Sold as is.
