This Broadway Limited Class AC4 4-8-8-2 Cab Forward steam locomotive is based on the "backwards" engines introduced by Southern Pacific designed for use on lines with many tunnels. In the 1920's, the SP had a need for powerful locomotives, but found that the new articulated 2-8-8-2's did not work well for them. They were a hazard to the crews when traveling through the long tunnels and snow sheds on their system. The exhaust fumes were capable of blinding and suffocating crewmembers, so to resolve this problem, the Southern Pacific decided to orient the locomotive in reverse. The next articulated engines from Baldwin were built with the cabs in the forward position and smokestack at the rear behind the crew. The SP went on to build many classes of these Cab Forwards. This locomotive features full Paragon3 sound and DCC for realistic sound and motor control. The Paragon3 sound system works with all Broadway Limited Rolling Thunder(TM) advanced sound systems. Other features of this steam locomotive include a heavy die cast chassis, smooth-running flywheel-equipped drive, directional lighting and magnetic knuckle couplers. This HO Scale Class AC4 4-8-8-2 Cab Forward locomotive can be operated on all DCC systems as well as on standard DC railroads (with limited sound functionality). This model has wheels profiled to operate on Code 70 and larger rail and curves of 22" radius or larger.
Although the prototype Class AC4 was used for hauling heavy freight on mountainous mainlines, Broadway Limited brings you a "what-if" version decorated in the SP's famous Daylight scheme.
