I took a piece of ME weathered track and just tapped the outside of the ties slightly and slowly in one direction, one tie at a time. It formed a curve easily. I went back over it slowly to make a tighter radius.
I had already laid all my curves with Atlas flex so it was just a test. I tapped all the ties ends back and the track went back straight. If I had known this earlier, I would have attempted to use ME track on at least one of my main lines.
If anyone has a piece laying around, try this. Just tap lightly and very slightly so you don't crack the plastic ties. Keep going over the area until you get the radius you want. Don't do it all at once!
