I just posted a couple of pics in my Cascade Branch thread that show how I handled this recently:

I’ll repeat those pics below. Here’s a pic from the angle this scene is usually seen from before it received some color. At the left side of the mountain in the middle there’s what looks like a cut.
Here’s a better angle in a couple of pics before the Sculptamold went on.
Essentially, it’s a tunnel disguised by overhang to look like a cut.
Here are two pics that reveal it from a pop-up that operators normally wouldn’t see.
I need to get in there with some black paint to darken things up.
On the other side, the branch’s entrance to the next room comes after the upper line of the two depicted here ducks behind this mountain in the corner of the main layout room.
