Model Train Tunnel – O Scale (Easily Scalable)

This tunnel was designed to fit Lionel O Scale train track. It's a clean, simple print that drops right into your layout. I based it on a multi-scale tunnel portal but resized it specifically for O Scale.

You can easily scale it up or down to use with other gauges like HO or N, depending on your layout needs.
