Massive Pressure in the Boiler
In 1936, the Schwartzkopff Berlin Machinery Construction Company, Inc. delivered the first class 41 fast freight locomotives. These units turned out to be general-purpose locomotives for medium weight trains. Between 1936 and 1941, a total of 366 locomotives of this class were built, of which most were taken over after the war by the German Federal Railroad and the German State Railroad.

Prototype: Class 042 freight steam locomotive with oil main firing and a type 2´2´T 34 standard design oil tender. Converted version with a new construction high-power boiler. German Federal Railroad (DB). Black/red basic paint scheme. Witte smoke deflectors, DB Reflex glass lamps, and inductive magnets on both sides. Locomotive road number 042 206-3. The locomotive looks as it did around 1970.

The locomotive has an mfx+ digital decoder and extensive sound functions. It also has controlled, high-efficiency propulsion with a flywheel, mounted in the boiler. 4 axles powered. Traction tires. The locomotive and tender are constructed mostly of metal. The 7226 smoke unit can be installed in the locomotive. Triple headlights change over with the direction of travel. They and the smoke unit that can be installed in the locomotive will work in conventional operation and can be controlled digitally. Maintenance-free warm white LEDs are used for the lighting. The close coupling with a guide mechanism between the locomotive and tender can be adjusted for different curves. There is a close coupler with a guide mechanism and an NEM pocket on the back of the tender and the front of the locomotive. The minimum radius for operation is 360 mm / 14-3/16". Piston rod protection sleeves, brake hoses, and prototype coupler imitations are included.
Length over the buffers 27.5 cm / 10-13/16".
