Nine rail cars loaded with pipe separated from a train and hit a trailer laden with sheet rock before slamming into delivery vans.
  The Alaska Railroad says in a release the accident happened Monday night during a switching operation in Fairbanks.
  There were a total of 15 cars involved in the accident, but six were empty.
  The loaded cars hit the trailer, then rolled over a stack of plywood and hit two box delivery trucks, stopping just before a commercial supplier's building.
  The train was going to Flowline to deliver the pipe.
  There were no injuries, and the railroad is investigating the cause of the accident.
