An almost rudimentary engine that was the first built by August Borsig. Basically a copy of the Norris type then running on the Berlin-and-Potsdam, this engine had a longer boiler and a rear carrying axle for the firebox. The steam dome was perched over a conical section extending up from the grate. Although more powerful than other engines under consideration, the BORSIG suffered from reliability shortcomings and was retired by 1850. 5 more 4-2-2 Borsigs were built before the BEUTH, a 2-2-2, was introduced.
