I wanted the streets track to be at ground level so I painted and cut a bunch of foam core but I don't like the way it looks. Do you have a better idea? Under the foamcore is Homasote so I can't recess the track in it. If it makes any difference there's about 30 feet of track and the base is 32 inches wide.
Thanks

I'm not sure that there is anything wrong with the foam core. It just needs to be finished and hidden by ground cover. I would seal up all the gaps (including the ones between the street and the foam core) with masking tape. Then apply your ground-cover of choice and It will look great. One approach would be a skim coat of drywall compound or Durham's plaster.
I don't know what you are intending for this scene. I would consider doing something to soften the "pancake flat" look. At minimum, I would consider another irregularly-shaped layer or two of foam-core, again transitioned with masking tape. Even tiny differences in elevation add great interest to a landscape. If it is a rural area, I would sculpt some pink foam. I would use the opportunity to introduce a few subtle road cuts. Even if you want all the track to be flat, there are plenty of opportunities for vertical relief in other areas.

. Thought about sealing cracks with joint compound or Durhams but concerned about the liquid in them swelling the seams. That is the main problem. I don't like the seams. I did seal both sides with Minwax polyurethane before I painted but I don't know if it soaked into the sides.

That is what the masking tape is for. It keeps the spackling material out of the cracks.
