Three train engines and ten railcars derailed in Slinger, Wisc. last night, spilling 5,000 gallons of diesel fuel, and injuring two people. More than 100 homes were evacuated after the incident, NBC reports.

A Canadian National Railway train derailed at about 8:30 p.m., then collided with another train, according to Reuters and the Chicago Tribune. Two crew members sustained non-life-threatening injuries, and a nearby propane tank exploded after the crash.

Hazmat officials put equipment in place to contain the diesel fuel, which spilled from the engine of one of the derailed trains. The cause of the crash is under investigation, and Slinger residents were allowed to return to their homes this morning.
