At the Nuernberg Toy Fair in 1952, Fleischmann first began presenting its very own lineup of HO scale models. Building off their prior preference to use 2 rail DC, the technology was implemented into the HO scale, making Flesichmann the first company to offer such a product line. Since its early introduction, it was the company's intention to completely exploit this technology, and give its fans the opportunity to determine the direction of the trains in advance. The tough metal tracks with discreet cardboard sleepers was indication of Fleischmann's objective, and was the base for the perfected track line used in layouts today. In conjunction with the track, and a full assortment of accessories for the layout, HO tycoons were presented with a class 01 tender loco, a class 80 tank loco, and a class E44 electric loco since the very origin of the product line.

During its existence Fleischmann has continued to release extraordinary products with the knowledge that modelers have a passion for control, and absolute realism. Fleischmann offers a model track with full profile rails, "Thinking" turnouts, a super-model turntable, and even a "Rack & Pinion" railway. Its more recent lineup includes the PROFI label, which consists of the pre-ballasted track, PROFI couplings for true close coupling operation, and even the tilt technology found in both the Pendolino and the ICE-T express train. For the Millennium, Fleischmann introduced Twin-Technik state of the art digital technology. All of the company's achievements including its multi train technology, make Flesichmann the pinnacle of model railroading.
