Today Maeklin is proud to announce the last new item for 2016: A giant at over 42 centimeters / 16 inches. A close relative and as impressive as the legendary Big Boy. A converted version with an oil tender with road number 3706 looks like it did in the fifties. The original locomotive had its performance test in a mountain ride in Wasatch mountain, which was commented by its chief engineer with “met the challenge”. The name “Challenger” remained for the locomotive. The model comes with a mfx+ Decoder under the Märklin article number 39911. The Trix article number is 22939.
