Burlington Northern Santa Fe spokesman Gus Melonas says the line reopened at 5:45 a.m. Friday although work continues in the Interbay switching yard.
He says minor damage to one of the tankers can be repaired in the rail yard. Workers still have to pump out the oil from a two other tankers that tilted so they can be repaired elsewhere. That will be next week.
No oil spilled, but the derailment of a train hauling 100 tanker cars of Bakken oil from North Dakota alarmed environmentalists and regulators. The train has continued on to a refinery at Anacortes.
The state Utilities and Transportation Commission is investigating.
