SEATTLE (AP) — A freight train derailment on the Tacoma waterfront dumped a ton of soybeans along the tracks.

Gus Melonas of the BNSF Railroad says four cars loaded with soybeans derailed at about 10:45 p.m. Thursday.

Two of the cars remained upright and two others landed on their sides, spilling tons of soybeans along the tracks.

The train was heading to a facility to unload when the derailment happened. No one was injured.

Investigators are still trying to determine what caused the cars to go off the tracks.
