There were at least 166 train-school bus collisions known to have occured between 1902 and 2000. Of these, 35 resulted in fatalities to school bus passengers resulting in 192 deaths and at least 546 injuries (some reports only indicate "many injuries"). The first known train-school vehicle collision occurred in
1902 when a train rammed a horse-drawn stagecoach in school transportation service resulting in eight student fatalities. The collision occured in West Nyack, N.Y., not far from the scene of the Congers train-school bus collision 70 years later.
