There was a glowing tail following the fireball as it fell and was almost as bright as the fireball itself (is that the same as a train?) It disappeared (stopped glowing) at about the same time as the fireball itself. The trail was approximately as wide as the diameter of the fireball, and there were one or two smaller chuncks that appeared at the edge if the tail that glowed brighter than the rest of the streak following the fireball.
One or two smaller glowing balls appeared along the top edge of the tail, glowing brighter than the rest of the tail. Appeared maybe half the size of the fireball itself
