Details This model platform system is ideal for use with Peco N Setrack, Streamline and any other unit trackage system which conforms to the same geometry. The two sections in this pack make a 288mm long platform plus ramps; it can easily be extended by simply clipping in additional ST-94 Stone type platform units. As supplied the units fit a standard track configuration but it is easy to adapt to suit other situations; just cut the platform surfaces to any of three widths by following the scribed lines on the back. Ramps can be made to one of two widths, and have curved sides to match the Setrack curve. Other Stone Style Platform Sections are available to add to this kit.
