NATIONAL BRIEFING / WISCONSIN

A freight train smashed into a minivan stuck on railroad tracks, injuring a police officer and a man who scrambled to pull his wife and young son to safety.

The woman and 2-year-old boy were unhurt, said Jim Gage, Elm Grove’s police chief.

Officer John Krahn, 41, was in satisfactory condition after surgery, said Kim Wick, a hospital spokeswoman. Scott Partenfelder, 47, remained in surgery after more than seven hours, she said.

It wasn’t clear why the van driven by Monica Ensley-Partenfelder, 40, was on the tracks. Scott Partenfelder had been traveling behind the van in another vehicle with two other children, Gage said.
