Not sure if technically a train, trail or it was so fast my eyes didn't process it correctly. There was a short white light trail.

Remarks
The object started as one huge piece then broke into several small pieces while still maintaining one large piece (white). The smaller pieces kept the same speed as the larger but turned from white to yellow to brownish yellow until gone. The large one maintained white until gone.
