A Canadian Pacific freight train carrying crude oil through Wisconsin derailed on Sunday, knocking 13 cars off the tracks, spilling oil and leading 35 homes to be evacuated, in the state's second derailment in two days.
No one was injured in the 2 p.m. incident in Watertown, about 80 kilometres west of Milwaukee, and workers stopped the leak, which company spokesman Martin Cej described as minor.
Late Sunday night, the company said 35 homes had been evacuated as a precaution, and that it had reserved hotel rooms for the families who lived in them.
