Nine flat railroad cars loaded with pipe separated and rolled away during a switching operation at the Alaska Railroad's Fairbanks yard late Monday.
No one was injured, the railroad said in an email Tuesday. The nine loaded flatcars hit a small trailer loaded with sheetrock, rolled over a stack of plywood and shoved into two box delivery trucks.
The cars rolled 672 feet, said railroad spokesman Tim Sullivan. The yard is almost entirely flat, Sullivan said. They didn't roll fast, but they also couldn't be stopped.
"Once it started moving, there wasn't anything they could do," he said.
