This modular track system features nickel-silver rails fully integrated to 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 roadbed; tack down track sections and file rail connections smooth after soldering. Simply snap it together and you're ready to go. UNITRACK, the modular track system from Kato Precision Railroad Models, can help you attain operating enjoyment in a fraction of the time and effort required for conventional track. Kato, one of the most respected companies in the model railroading industry, manufactures UNITRACK. When UNITRACK was first introduced over ten years ago, there wasn't much else like it. Today, even though other manufacturers have followed the lead set by UNITRACK, nothing else comes close. At the heart of UNITRACK is the patented UniJoiner. Remarkably simple and undeniably reliable, the UniJoiner is the key link that makes UNITRACK unique. Because of the UniJoiner's dependability it is not necessary to solder rail joints. UNITRACK can be used in nearly any layout situation - large or small, permanent or temporary. UNITRACK can be the answer for the beginner looking for a trouble-free introduction into model railroading without the frustration and disappointment of rail and electrical problems. UNITRACK also meets the needs of advanced hobbyists, providing superior quality to an entire layout or the flexible solution to the ever-changing staging yard. There is nothing quite like a model railroad, completely capturing your imagination as a model train runs down the rails. With UNITRACK, there is less work to experiencing the enjoyment and being actively involved in the hobby model railroading. 248mm (9 3/4)
