What it does
- Detailed double-door relay box for OO scale layouts
- Sits next to signals and crossings for that real-world feel
- Adds depth and story to plain track sections
- Fits standard OO gauge scenery placement
- 3D-printed and made in the USA
Bring more life to your model railway. This OO gauge relay box gives your layout the line-side detail real railroads have. Place it next to a signal, a level crossing, or a points lever and the scene starts to feel real.
The double-door front and the boxy shape match the prototypes you see along real tracks. It scales to OO gauge so it fits the standard 1:76 layout. Drop it in next to a signal post and the eye reads the whole scene as more believable.
Made in the USA. A small but powerful detail piece for any OO gauge railroader who cares about scene-building.
