Hornby R638 Roll of track foam underlay Approx: 4880mm (16ft)

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