I viewed the fireball from my car, and I first saw it down the side street of the intersection. It seemed to be going up slightly at first, and then angled down and I lost sight of it when it fell behind the buildings.

The train looked gold and appeared to spark like a sparkler. It appeared to be an isosceles triangle with the point trailing behind the fireball, and the base angles being approximately 80 degrees.
