A freight train carrying 100 cars of crude derailed early Thursday morning in Seattle, the Seattle Times said.
Five cars jumped the track when the train was pulling out of the Burlington North Sante Fe (BNSF) station going 5 mph.
Engineers inspected the tankers and found no leaks.
One of the derailed cars was loaded with sand, and four others were carrying crude.
The train was loaded at Bakken and was headed to a refinery in Anacortes, Washington, the Seattle Times said.
A BNSF spokesman said the derailed cars are newer models with enhanced safety features to safeguard against spills.
No evacuations were necessary.
No injuries were reported.
The cause of the derailment has not yet been identified.
Engineers are working to put the train back on the tracks, KIRO-TV said.
