TRACKRITE H505D HO Gauge Track Underlay - Thick and Flat (5m)

Flexible foam underlay helps create a prototypical track bed profile, with a raised surface and natural slope on either side to glue your ballast. It also assists with dampening noise, helping to reduce the accoustic ressonance of your layout.

Refer to the chart on the left when selecting which underlay to use. The standard profile is bevelled on both sides, but you can use a squared off edge to combine the underley with that of a parallel line. Use flat underlay when modelling complex point work or railyard areas.
