As trains don't like climbing up a curb, we had to come up with another option.
How about insetting the MDF?
We were going to try it with chisels and a utility knife, but then decided to consider power tools so this would get done before the sun cooled.
A buddy had loaned me his router to let me clean up a couple of other places on the railroad, so we took a test plunge with it on homasote. We learned that routing homasote makes a tremendous amount of dust, so you must run a vacuum around the same time and be prepared to continue to vacuum up stuff after the router is off. (Even better would be trying it outside, BTW, but I've killed a bunch of grass doing that..)
But it worked.
As we needed a sloped inset, a test fit and measurement was called for.
