When I built the oldest part of my layout over 20 years ago, I made a mistake. I put a Ross switch at the top of a grade, with downgrades on both sides. It was a recipe for derailments. I have made a variety of interventions to create a level area on both sides of the switch, but derailments continue, although certain equipment seem to be part of the problem. The switch itself has become damaged from all the accidents. I plan to replace the switch and want to address the vertical curve issue at the same time. I want to lengthen and reduce the steepness of the grades adjacent to the switch. I don't think I can move risers. I'm looking to put something under the Homasote sub-roadbed that would provide the gradual grade needed. What ideas do you have?

How about starting with some pictures of what you have so we can better visualize it. It sounds like the problem is likely the lack of grade easements approaching the summit, that would be a recipe for derailments.
If your homosote is flat on a table top, you'll need something solid under it the whole length of the grade easement so you dont end up with a roller coaster. Only idea that comes to mind (without pics of your existing configuration) is to cut a giant wedge out of a long 2x4 using a table saw. Or, add a new plywood sub to the homosote and build up what you need out of risers.
Maybe Woodland Scenics incline sets? You could take 2% ( or 3% or 4%) out of the grade that way.
I bit the bullet and am removing all the risers. 4 came out easily: unscrew screws under the layout. Two others required cutting my preliminary scenery just below the baseboard to get access to the risers. The last was not originally a riser, but a 2x3 brace under the grade baseboard, which is now resting on the lower layout surface. I've started sawing it to half length, but quitting time came.
My plan is to to have no grade through the switch, or for a car length after, with a much reduced grade beyond that.
Can I just say how much harder it is to rebuild a poorly built section of layout than it is to build it right the first time?
I read a article once that said, that you should never beat yourself up for making mistakes. Everyone does, or they are extremely lucky. If everyone spent the time, money and experience planning to do everything right the first time, very few things would be done. It is as important that you got your layout running and now you have the pleasure of making it better.
How could you learn and improve without mistakes or wrong paths taken ?
I had to memorize that poem in 8th grade English class. Long gone now.
