On October 22nd, 1937, in Renwick, Iowa, United States, 28 students from Renwick High School were on a field trip with two teachers in Mason City. The students had spent the day touring various industries in town, and their second to last stop before heading home was Mason City Brick and Tile. Unfortunately, the bus would never make it to the next facility. As it headed down the road from the factory, it was struck by a train, which split the wooden bus in half.
