As the waterworks continue, David details his process for creating realistic waterfalls for the Olympia & Sand Creek On30 logging layout. He starts by making flexible waterfall sheets using multiple coats of Woodland Scenics water effects paste on plate glass. He also shows how to build containment dams across the river rocks using clear silicone caulk to hold the forthcoming resin pour. Finally, David cuts the clear, flexible material and glues it over the dams to shape an authentic, natural flow around the rocks. Join us next time for the resin pour, as the complete Olympia series continues…exclusively on Trains.com Video!

  1. David, love these videos. When this section is complete, be sure to include an updated series on operation to include the entire railroad (all three sections).

    Thanks again, your work is spectacular!
