Rail lines have been reopened, and crews are cleaning up, a day after a Canadian Pacific train carrying tens of thousands of litres of crude oil from Alberta derailed in western Minnesota.

CP Rail spokesperson Ed Greenberg told CBC News that full track repairs had been made and the cleanup is "progressing well."

According to CP Rail, 14 cars on a southbound train derailed near Parkers Prairie, Minn., before 7 a.m. local time Wednesday morning.

The 94-car train was headed to the Chicago area.

Minnesota Pollution Control Agency spokesman Dan Olson said an estimated 75,600 to 113,400 litres of oil spilled or leaked.

Olson said one heavily damaged car spilled much of its 98,280-litre load. He says the oil was "just oozing out" in the cold.  

Olson said because the ground is frozen, there's no threat to water. 

CP Rail spokesman Ed Greenberg said Wednesday evening that response protocols were implemented immediately.

Greenberg noted that no injuries were reported and said the derailment didn't pose a public safety risk.

An investigation into the cause of the derailment continues.
