This modular track system features nickel-silver rails fully integrated into a remarkably realistic-looking roadbed. The patented Unijoiners (included) lock the track sections together firmly and evenly. The frustration of derailments resulting from uneven rail joints and separating sections is eliminated.
There's no need to glue down cork roadbeds; tack down track sections and file rail connections smoothly after soldering. Simply snap it together and you're ready to go.
The telescoping track section expands from 3" to 4-1/4" 78 to 108mm.
