Product Overview

With the advent of diminished locomotive production due to World War II demands and restrictions, many western railroads were hungry for top performing and even more powerful steamers. A number of railroads believed the most suitable of these was the articulated Challenger. A behemoth of its day, it boasted enough horsepower to haul both freight and passengers in excess of 80 miles per hour, with all the efficiency and torque required to run up steep, mountainous grades. The Challenger was an incredible iron workhorse that left its legacy and imprint on the world of railroads and rail transport.Now these highly accurate scale locomotives are available for the first time in American Flyer S Gauge. Experience the thrill of operating the rail hugging monsters on your very own layout. These outstanding locomotives have been created with a level of performance and detail never before seen in American Flyer S Gauge, including the LEGACY Control System.
