BR 53 Borsig Steam Locomotive Condensation Tender. 2011 Toy Fair Locomotive DB class 53 “Borsig” painted in the WWII Wehrmacht “Winter Camouflage” paint scheme. Locomotive is in new condition, Cleaned of old lube and re-oiled, tested fine. Steam Locomotive with a Condensation Tender. Study for a prototype by the builder Borsig-Werke in Berlin, with the addition of a condensation tender from Henschel in Kassel. Mallet design with high and low pressure cylinders. Version for long runs, with a boiler water recovery system in the tender. The locomotive has a 5-pole motor. Both groups of driving wheels are mounted to pivot and all 7 driving axles are powered. The headlights are maintenance-free LED’s. Minimum radius for operation 145 mm / 5-11/16. Length over the buffers 143 mm / 5-5/8. The design presented by Borsig envisioned a Mallet design articulated locomotive with 4 cylinders. With an output of almost 3,000 horsepower and an axle load of under 20 metric tons, it would have been able to reach a speed of 80 km/h / 50 mph in both directions and pull a train of 1,700 metric tons over an 8% grade at 20 km/h / 13 mph, even on curves with a radius of 360 meters / 1,181 feet. The Borsig engineers were never able to prove these theoretical performance data; a working prototype was never built. At the end of 1943 at least the running gear, the frame and boiler were supposed to have been built for the first unit of this immense locomotive; the large tender had not been built yet, however. The construction of such a prototype surely was a lesser priority than the ongoing production of other locomotives. At this time in Germany, for all practical purposes only the heavy class 42 locomotives and particularly the maneuverable class 52 locomotives were still being built in considerable quantities. Moreover, the war damage at Borsig in Berlin was so devastating that regular production was no longer possible? In 1944 just 2 more Borsig locomotives were finished. The current orders as well as many still usable machines and material were finally moved for the most part to Henschel in Kassel. This gave new potential again for the project for the large Mallet locomotive. Instead of the high-capacity tender planned for the locomotive, the high demand for water for the four cylinders could also have been covered by the existing Henschel condensation tender, type 3´2´T16. The condensation process would also have enabled a synthesis of high performance and relative economy in this super large locomotive. The class 53 was never converted into a condensation locomotive; the required design changes for this secret project have also not been documented. The locomotives that followed could only be equipped with the type 2´2`T13,5 tender, and this tender was much too small for the Borsig locomotive. So, it remained an idea, a second concept for the largest German steam locomotive, which after a pause in development of 63 years is still being realized at least in the scale of 1:220. Both groups of driving wheels are powered. Locomotive body constructed of metal. The largest MARKLIN locomotive for the smallest model railroad: Length over the buffers 143 mm / 5-5/8.
