Inspectors from state and federal agencies will be inspecting the railroad track from Pasco to Vancouver this week on the Washington and Oregon sides of the Columbia River.
The inspections are in response to the derailment June 2 of an oil train derailment in Mosier, Oregon. Sixteen cars carrying crude oil to Tacoma, Wash., derailed and four caught fire.
The Washington State Utilities and Transportation Commission has sent two federally certified track inspectors to work with the Federal Railroad Administration to check tracks on the Washington side of the river, which is a BNSF line.
Oregon Department of Transportation inspectors will help with inspections of the Union Pacific line on the other side of the river. Both states are ensuring all federal track safety standards are being met.
Union Pacific said at least one bolt holding the rail in place near Mosier failed at a curve in the track, causing the derailment. The company is checking similar bolts used where tracks curve in 23 states.
