The actual train is the world's largest steam locomotive belonging to the Union Pacific Railway, and it was revived in 2019 after 60 years since its retirement in July 1957, and became a hot topic.

◆Introducing the sound card of BigBoy, the super-large locomotive that symbolizes the railroads of the United States. Since its revival, the faces of the modern Union Pacific Railroad and its continued use as event trains are shown as "126-4014 Union Pacific Railroad Big Boy #4014", "UP Water Tender".You can enjoy it with vehicles such as "UP Excursion Train" and sounds.

◆This product is a "controller synchronization" type that can be enjoyed even by sound card beginners. It is also equipped with a program for the "save tuning settings" function. The controller priority mode ON/OFF settings are saved, so even those who are just starting to drive with a sound box can enjoy it easily.


  • You can enjoy an immersive railway model experience while feeling the realistic changes in running sound depending on the running conditions.
  • By operating the throttle (power pack controller) and 6 function buttons, you can create a <Big Boy> performance with sounds such as running sounds and equipment sounds.
  • Includes a quill whistle with pitch changes and conductor announcements on the station platform that will further enliven the atmosphere of the revival event.
  • You can experience the power of "Big Boy" with high quality and high volume sound from the sound box itself and external speakers.
  • Controller synchronized sound card that is easy to play even for first-time users
  • Equipped with a "save tuning settings" function that remembers the previous tuning mode when the sound box is powered off and maintains the settings the next time it is turned on.
  • A "function label" compatible with the sound box is included in the package.

    This sound card is loaded with the basic sounds of the UP Big Boy, but when played through the Kato sound box, they sounding absolutely fantastic, giving more depth and life to any scale/gauge UP Big Boy.
    Kato's sound cards are highly recommended for suitable analogue locomotives or for general railway atmospheric sounds.
