Dozens of homes in Slinger were evacuated Sunday evening after a train derailment prompted fears of a possible fire from diesel or other fuel. The accident occurred southeast of the crossing of two separate freight rail lines Wisconsin & Southern Railroad and Canadian National Railway Co. at state Highway 144 in the village in the general vicinity of the high school. Slinger Fire Chief Rick Hanke said three engines and ten railcars derailed, forcing the evacuation of more than 100 nearby homes. About five thousand gallons of diesel fuel spilled from an engine,. Hazmat crews had dikes and booms in place. Patrick Waldron, a spokesman for Canadian National Railway Co., confirmed there were two crew members on board the train. They were injured and transported to an area hospital to be treated for non life threatening injuries. Preliminary reports indicated the southbound train struck another set of cars on another train. The circumstances are under investigation. There was no official confirmation late Sunday night whether track conditions or speed played a factor in the derailment. All residences a half-mile south and east of the crossing were evacuated as a precaution, according to Slinger Fire Chief Rick Hanke. The evacuation extended from Kettle Moraine Drive, or Highway 144, east to Slinger Road, and the rail crossing south to state Highway 60. Slinger Middle School was opened as a temporary shelter. Families have now been allowed to return to their homes. The clean up at the crash site continues this morning.
