  • Product description

    Model: The locomotive has an mfx digital decoder and extensive sound functions. It has a controlled high efficiency propulsion motor with a bell-shaped armature and a flywheel, located in the boiler. 5 axles powered. Traction tires. The locomotive and the tender are constructed mostly of metal. A 7226 smoke generator can be installed in the normal smoke stack. When the locomotive is running, the smoke stack can be closed with a hatch. The triple headlights that change over with the direction of travel and the smoke generator that can be installed in the locomotive will work in conventional operation and can be controlled digitally. The headlights are maintenance-free, warm white LEDs. There is a close coupling with a guide mechanism between the locomotive and tender. The front of the locomotive and the back of the tender has a close coupler in an NEM pocket with a guide mechanism. The coal bunker hatches can be opened and closed by hand. Minimum radius for operation is 360 mm / 14-3/16". Piston rod protectors are included.
    Length over the buffers 26.4 cm / 10-3/8".

  • Prototype information

    After intensive experiments with the two class 42.90 Franco-Crosti locomotives, the German Federal Railroad decided to convert several class 50 locomotives in the same manner. A Franco Crosti boiler is a conventional locomotive tank with a second boiler connected in the steam lines. It heats feed water with the assistance of smoke exhaust gases passing over the water. This second boiler is therefore called an exhaust gas pre-heater. The Italian designers Franco and Crosti built their first test units with this technology as early as the Thirties. The savings in coal were approximately 20 % with the improved efficiency. The flat smokestack for operation projects from one side of the boiler, which results in a rather striking appearance. The standard smokestack no longer serves to discharge smoke exhaust gases during operation, but is only required for firing up the locomotive. Relatively high operating costs resulted despite the increased efficiency, since the pre-heater boiler was easily subject to corrosion. A total of 31 locomotives were delivered to the German Federal Railroad by Henschel in 1954 and 1958, and were designated as the class 50.40. These two-cylinder, 90.6 metric tons heavy locomotives had a maximum speed of 80 km/h / 50 mph in both directions and an indexed performance of 1,540 pounds per square inch. They were used in the Münsterland area and in the Rhine area in freight train service until they were retired in 1967 and then scrapped.
