Has anyone got advice on the foam incline sets

[deckroid]

... then set some old Physics textbooks on top to hold it overnight...

2nd best use of old Physics textbooks if I ever heard one.

I, too, use the scenics foam inclines. I have a 2% up and 3% down. Every engine I own can run up the 2% with a load of cars with no issue. They may slow down, but that's prototypical, isn't it? The only issue I can see for the 2% grade is the length. If you have the room for it, it's great. But it runs 16 feet... that's quite a bit of real estate.
