Three cars from a 102-car oil train derailed under the Magnolia Bridge in Interbay around 2 a.m. this morning (July 24). The cars, carrying oil and sand, did not spill.

Crews are in the process of re-railing the cars, a Burlington Northern Sante Fe spokesperson told Crosscut News. The tracks are expected to be held up for the next five to eight hours.

The train was going 5 mph when it went off the tracks. The train was delivering crude oil from North Dakota.

No injuries were reported.

The cause of the accident is under investigation, the spokesperson said.

Yesterday, the federal government “proposed rules that would phase out tens of thousands of older tank cars carrying crude oil and other highly flammable liquids,” according to The Seattle Times. There have been 10 major derailments in the United States and Canada in the last six years, often ending with huge fireballs.
