Not sure if you want your tracks buried in the ground or paved over, but do check out Bob Smaus’ Port of Los Angeles project railroad (late 1990-early 1991 MR, or “6 Project Railroads” book). Most of the tracks are paved over with Sculptamold to simulate track in asphalt/concrete driveways, but they transition to a ballasted mainline. In any case, grab a scrap piece of whatever your sub-roadbed material is and some old flex or sectional track and try experimenting. Cheers.
Here’s a shot of my old/not used coal tower, with some unused tracks. I just used some ballast, and some foliage. I got the track ties hidden, but the rail still exposed.
There is some tracks near me thats not used anymore. It has grass grown all over it, and that would be a good idea. I will try to get a shot of it this morning.
