Hornby R626 4 Point Underlay Sheets

Four sheets 267mmx89mm each, for cutting and fitting under trackside accessories that have to raised to the level of the track. 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.
