Story highlights Authorities are evacuating 100 homes due to diesel concerns

Two people are injured

Two trains collided in southeastern Wisconsin on Sunday night, causing 5,000 gallons of diesel to spill, a fire official said.

Three engines and 10 rail cars derailed at a point where the tracks crossed, Slinger Fire Department Chief Rick Hanke said.

Residents within a half-mile radius were evacuated due to concerns over the flammability of the diesel and contamination from the spill, Hanke said. More than 100 homes are in the evacuation zone.

A conductor and an engineer suffered injuries that are not life-threatening, the fire chief said.

The crash involved cars carrying sand and lumber. They came from CN and Wisconsin & Southern railroads.

Slinger is about 30 miles northwest of Milwaukee.
