Gov. Jay Inslee called for a halt on Union Pacific Railroad oil trains traveling through Washington on Friday until stricter safety standards are enacted.

Inslee’s call comes after an oil train headed to Tacoma derailed in the Columbia River Gorge, in the town of Mosier, Ore., earlier this month. Oregon’s Gov. Kate Brown and other political leaders called for a moratorium on oil transport in response to the fiery crash. Inslee’s call for curtailing Bakken oil traveling through the state focuses solely on Union Pacific.

Jamie Smith, Inslee’s spokeswoman, said Inslee’s call for a “moratorium would essentially apply to UP (Union Pacific) since they aren’t doing adequate inspections,” but added, “the ask is to halt any Bakken oil trains that haven’t been cleared by a walking inspection by the railroad.”

BNSF Railway has inspectors who walk the tracks, Smith said. BNSF is the primary carrier of oil in Washington, according to state data.

“Ideally, FRA (the Federal Rail Authority) could halt all oil trains that don’t have all the safety improvements, electronic brakes, newer cars, but that doesn’t appear to be within their authority,” Smith wrote in an email, adding that’s why Inslee is focused on stopping all oil trains until walking inspections are mandatory.
