The Wollaston disaster was a railroad accident that occurred on October 8, 1878, in the Wollaston neighborhood of Quincy, Massachusetts. 19 people were killed and 170 were injured when an incorrectly-placed switch caused the derailment of an excursion train returning from a sporting event. The conductor who placed the switch was convicted of manslaughter, but the conviction was overturned on appeal.
