Bluetooth Music Rolling Stock by Golden Gate Depot

This isn’t a sound decoder.
This isn’t locomotive audio.
This is music on the rails.

Golden Gate Depot introduces the Skybox Rail-Shaking Audio Car, a Bluetooth-enabled rolling speaker system built directly into a 100% prototyoical Skybox freight car. Inspired by custom rolling stock installations pioneered by Moody Locomotive Works, this car turns your train into a moving sound system, delivering powerful, room-filling audio straight from the consist.

What It Is

The Skybox Rail-Shaking Audio Car is a Bluetooth speaker system hidden inside a Skybox carbody, designed to play your own music as your train rolls. Connect your phone or tablet, cue up a playlist, and let the train do the rest.

No decoders.
No programming.
This car is about music, presence, and atmosphere, not necessarily prime movers or horns (but it can be if you so choose).

Why It Exists

Trains move.
Music moves.
Layouts should feel alive.

Whether it’s rock, jazz, synthwave, ambient, industrial, or anything else you choose, this car adds a completely new sensory layer to O Scale railroading. The sound travels with the train, filling the room as the consist passes, something stationary speakers simply can’t replicate.

.
It’s about experience.
