Steam 4-8-8-4 "Big Boy" Powered w/Tender - Digital -- Union Pacific #4011 Silver & Black

The Big Boys have a powerful five-pole can motor with flywheel that provides the tractive power needed for realistic in-scale acceleration, speed and pulling power. The chassis and truck carriages are metal for better balance, a lower center of gravity and extra strength. Reduced diameter flanges on trucks and drivers allow operation on Code 70, 83 or 100 track. Now that the motor is concealed in the boiler, you'll find a fully detailed engineer's cab, firebox and controls.
