This product is a massive lot of HO scale Märklin 3 rail track, manufactured in Germany during the 1950s. The track is ready to go and pre-built, featuring an analog control system for operation. With a scale of 1:87, this vintage track is a collectible item for enthusiasts of Märklin brand products. Perfect for those looking to expand their existing HO scale train setup or create a new layout from scratch. Please note that I am unsure if this makes a full loop.
