Union Pacific Big Boy #4014 with Soundtraxx DCC & sound

Kato’s N scale Big Boy engine is a wholly new and unique design from any steam engine that has come before, utilizing two coreless motors in dual articulated metal mechanisms to power the 16 total driving wheels. Thanks to the articulated design just like the real engine, the two sets of driving wheels are able to move independently which gives the engine the ability to navigate 11″ radius curves, allowing the locomotive to run with Kato’s other large scale engines like the FEF-3 and GS-4. The engine also features pickup both from the drive sections as well as the tender for maximum electrical coverage and reliability, and will be fully ready to run no matter which variation you purchase with all details fit and ready to go out of the box, DCC + Sound, and operational lighting from the deck mounted forward facing headlight.

• Dual coreless motors with brass flywheels for unmatched pulling performance
• Weights carefully placed along the body even in the cylinders to give the engine perfect balance and weight distribution.
• Minimum radius 11″ (282mm)
• Operational tinted LED headlight
• 4014 has the iconic “Big Boy” chalk lettering on the front of the smokebox
• 4014 is built to match the 2021 Excursion tour appearance:
  • Oil Tender
  • Graphite Firebox
  • Silver cylinder head and piston covers
  • Builder’s Plate

Unit 4014 is immediately recognizable in its 2021 appearance thanks to the brilliant cylinder covers which harken back to the locomotives original look.

Unlike some engines like the FEF-3 or GS-4 which have a headlight on the smokebox door, the Big Boy has a deck mounted headlamp which turns along with the front of the engine.

The Big Boy is massive, with two individual sets of 8 drivers. From the side you can see the independently moving front deck and articulated driver sections.

Thanks to the articulated mid-body bend from the two independent motorized sections, the Big Boy is capable of navigating 11" curves, something that would be otherwise impossible for such a large engine.
