Back to Model RR Gallery HO SCALE TRAIN STATION Made from 1/2" thick foam. The walls and roof can be cut out using the Hot Scroll Table or Hot Knife. The lines for the wood slats and shingles are engraved with the Engraving Tool, or carefully with the tip of the Hot Knife. The doors and windows are cut out with the Hot Knife or on the Scroll Table. The door and window trim are cut out separately and glued in place. See the instructions and Foam Factory Instructional Video for tips on cutting holes (for windows) and angles (for roof and wall joints).
