In this tutorial we learn how to lay and ballast O-Scale 3-Rail track. First, lay the track down on a piece of bare plywood. Also, you will paint the wood to prevent it from absorbing liquid when you place glue on it. Put the track down onto a flex bed and then set the flex bed on the wood. From here, place the track onto the road bed and line it up. Make sure the track is centered completely. After this, take a track screw and secure the ends down. Continue to do this throughout the entire track and when finished use it for your train!
