Class 042 Steam Locomotive

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.

  • Intricate model, constructed mostly of metal.
  • Partially open bar frame and many separately applied details.
  • Controlled high-efficiency propulsion with a flywheel, mounted in the boiler.
  • World of Operation mfx+ digital decoder with a variety of operation and sound functions.
  • Product description

    Model: 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".

    Class 41 The locomotive industry developed the 2-8-2 class 41 locomotive for fast freight trains as part of the DRG's standard design locomotive program. The two sample units were delivered by Schwartzkopff in 1936. The running gear was a new development, and the boiler was the same as on the class 03. However, on the class 41 it was designed for 20 bar / 290 pounds per square inch. The axle load could be set at 18 or 20 metric tons. With the class 41 for the first time there was a general-purpose locomotive. The two pre-production units were followed by 364 regular production locomotives. There were slight improvements and almost all the German locomotive builders delivered them by 1941. The 90 km/h / 56 mph fast and around 1,900 horsepower locomotives were used in almost all areas. After World War II, 216 locomotives remained on the DB. The worn-out St47K boilers on the units soon presented a problem. Since the class 41 was indispensable, the DB developed a completely welded high-performance boiler with a combustion chamber as a replacement. Compared to the previous long tube boiler, this new one had a higher percentage of high-quality radiative heating surfaces and could sustain a higher load. Between 1957 and 1961 the repair facility (AW) at Braunschweig installed this new boiler in 102 class 41 locomotives, which in conjunction with the removal of the front skirting clearly altered the look of the class 41 units. Forty of these converted locomotives also benefitted from oil main firing. The last oil-fired converted units were removed from service in 1977.
