You misunderstood what I said. The tilting factor is (say) a percentage of track speed limit. Let's suppose it's 50%: you'll derail in a track of 10mph when you reach 16mph. If you raise the speed limit to 60mph (of same piece of track) you will derail only if you reach 91mph. I have a lot of scenarios in which I raised the track speed limit from 30mph (train derailling at 50mph or so) to 60mph for test purposes, and trains ran fine at 80mph, that's not a problem.
In other hand you can run at 50mph in a 60mph track, but if you lower the speed to 10mph you'll derail over 15mph with the same train in the same section of track.
