KM1

KM1 Modellbau was founded in September 2003 by Andreas Krug in Lauingen an der Donau, Germany, with a mission to redefine the technical boundaries of large-scale model railroading. Originally starting as a specialized workshop for refining existing models, the company quickly transitioned into an independent manufacturer, establishing its headquarters in a historic former power plant characterized by its iconic 48-meter-high water tower. From its inception, KM1 focused on the Gauge 1 (1:32) market, later expanding its expertise into Gauge 0 (1:45) and high-quality accessories for other scales, consistently prioritizing "precision in every detail" as its core philosophy.

The brand is globally recognized for pioneering "Dynamic Smoke" technology, a system that produces wheel-synchronous, rhythmic steam exhausts and independent cylinder steam, creating an unprecedented level of operational realism. Most KM1 locomotives are handcrafted from a combination of brass and stainless steel, featuring high-performance Faulhaber motors and integrated HiFi speakers optimized in the company’s own sound studio. This dedication to sensory immersion—combining synchronized sound, light, and motion—has positioned the brand as a leader in the premium large-scale segment, catering to collectors who seek museum-quality fidelity.

Operating with a tiered production strategy, KM1 offers the "Classic Edition" for those seeking robust, high-detail models at a more accessible price point, alongside limited-run "Premium" and "Fine Scale" editions for the most discerning enthusiasts. Their catalog focuses heavily on German railway history, from the early state railways to the modern era, and includes a full ecosystem of products from precision-engineered track and signals to finely cast figures. Today, KM1 remains a family-driven enterprise, celebrated for bridging the gap between traditional handcrafted brass modeling and cutting-edge digital technology.
