The Micro Feinmechanik test locomotives stand proudly as some of the most coveted and intricately detailed brass models ever produced. Among them, the H17.206 emerges as a rare masterpiece, meticulously handcrafted to perfection with only 40 models crafted worldwide. This locomotive is a testament to Micro Feinmechanik's unwavering dedication to excellence.
The model has an extensive cab interior, replicated braking system, completle test gear equipment, test cables, test pulleys, and a functional boiler hatch featuring elaborate boiler details, the H17.206 epitomizes the meticulous craftsmanship synonymous with Micro Feinmechanik. Its superior quality extends to a high-end brushless, ironless bell-shaped motor, a hallmark of Micro Feinmechanik's locomotives. This locomotive not only delivers outstanding running capabilities but also boasts exceptional detailing showcasing the pinnacle of precision engineering in the world of brass models.
Description:
Originally emerging from the S 10.2, No. 1201, the H17 underwent a fascinating transformation. Built-in 1917 at the Hanomag factory with the serial number 7434, it was initially renumbered to 20445 in 1925. A pivotal moment in 1926 saw the locomotive rebranded as the 17.206. This transformation included the integration of the "Schmidt-Hartmann" high-pressure boiler and a conversion to adhesion for the power train. The lighting system was upgraded to "Pinsch"-Gaslamps, and smoke deflectors were added. Its iconic 1926 livery featured a black exterior with striking red wheels and drive rods.
History of the Original:
BR H 17 206 of the Deutsche Reichsbahn-Gesellschaft
In the aftermath of World War I, the newly established Deutsche Reichsbahn sought innovative solutions to enhance steam locomotive efficiency, prompted by coal shortages due to the evolving political landscape. Drawing inspiration from the Swedish Ljungströms turbine locomotive 267 530, Krupp and Maffei locomotive works produced the T 18 1001 and T 18 1002. However, these attempts were not as successful as anticipated. Simultaneously, the H 02 1001 proved overly complex and faced numerous setbacks, never entering regular service.
An alternative approach emerged with the two-pressure system patented by W. Schmidt, proposed to Henschel locomotive works in 1925. The reconstruction used a former Prussian class S 10.1 (DRG class 17.2) as a base. Initial tests in the Magdeburg vicinity in 1927 were cut short due to defects and problems. Following extensive modifications, subsequent tests in February 1928 revealed a coal savings of only 8% compared to the Bavarian S 3/6 18 518 tested simultaneously. Despite efforts to address technical issues, the locomotive proved challenging, and by 1937, it was reverted to its original state.
