Split it down the middle and put in a canal. The split doesn't have to be parallel to the sides - you could have a diagonal canal. And, although it's a bit more work, you could have it curve and meander across, while maintaining a constant width.
A lot of the earliest railroad rights-of-way went right along the canal paths, perhaps crossing over when the canal made a sharper bend than the railroad could. This would give you an interesting modelling opportunity for short bridges and trestles.
It takes an iron man to play with a toy iron horse.
I'd move it forward, much easier to hide things in the back. You could also get more foam, fill in the gap or use it to build hills that will hide or be over the gap in the back.
Good luck,
I see that my foam sub-roadbed is slightly (about 2") narrower than the benchwork. Do I move the foam towards the front making flush w/ the front edge or leave it flush w/ the backdrop? I tried it both ways. Having it align along the front has the advantage of looking nice when I put in the masonite fascia. On the other hand, having it along the back covers up any paint errors from the backdrop. I guess I can cover that up also w/ scenery--trees, houses, etc.
Resolving this matter now is far, far, easier before I start laying down track and glue the foam down.
TIA!
