Happy New Year to all! I have a fairly large intermodal yard that is what I would consider almost complete (yes, until I expand it for the umpteenth time) but what it is missing is the ground surface. The entire layout is 3/4 plywood, covered in 2" foam painted a sand color and breadboarded in 1 x 8 clear pine. The reason the surface has not been completed is that I honestly have no idea what to use and how to use it. What do intermodal yards typically use? Every picture looks different on line. If there is a consensus for a particular substrate, where do I get it and what techniques. Any help this forum can give me would be greatly appreciated!
