Demon @SFGam Black Train Smooth As Glass?

Anyone else experience this? I was so suprized how incredibly smooth it was. Was it refurbished? I know when I rode a month ago (I don't normally ride it) it was still the same old arrow headbanger, this past friday it was amazing.

I think it's just regular train maintenance. I've ridden it when it was a horrible headbanger and when it was the smoothest looper in the park. My guess: new wheels.
