We recommend covering Inclines and Risers with Plaster Cloth before laying roadbed.
Instead of using cork, we recommend Track-Bed. It provides quiet and smooth train operation, and helps absorb sound irregularities from your layout. It requires no pre-soaking, remains flexible and it won’t dry out and become brittle as cork does.
Use Foam Tack Glue (ST1444) to adhere Track-Bed to layout base and track to Track-Bed.
