A Canadian National Railway Co. train struck another freight train as it rolled through a small village in Wisconsin, causing cars to derail, injuring two people and spilling thousands of gallons of diesel oil that prompted the evacuation of dozens of homes. The southbound Canadian National train struck several Wisconsin & Southern Railroad cars around 8:30 p.m. Sunday at a rail crossing in Slinger, according to Patrick Waldron, a Canadian National spokesman. Three engines and 10 railcars derailed, Slinger Fire Chief Rick Hanke said. Slinger is northwest of Milwaukee. An engineer and conductor on the Canadian National train were taken to a hospital with injuries that were not life threatening, AP quoted Waldron as saying Monday. About 5,000 gallons (1,890 liters) of diesel spilled from a locomotive fuel tank, Hanke said. Hazardous materials crews placed booms around the spilled fuel and crews worked to upright the derailed cars Monday morning. Some 100 people who live near the crash site were evacuated from their homes as a precaution but they were allowed to return around 1:30 a.m., Hanke said.
