A resilient foam underlay that fits under track to simulate a full-size ballast track bed. It also damps out vibrations so trains run more quietly and there is less chance of 'wheel bounce' to spoil performance. Approx. 4880mm long, this strip is the width of single track with indentations for fit the sleepers. The strip is flexible to follow any straight or curved track and is easily cut to make junctions at points and cross-overs.
