A 92-car Union Pacific train heading east spilled an undetermined amount of diesel fuel near Troutdale, Oregon, on Tuesday night.
The diesel leaked out of the locomotive. The cause was a fuel filter ring that failed, according to Justin Jacobs, a spokesman for Union Pacific.
The railroad has moved the locomotive to a location where officials can get a better sense of the amount of diesel that spilled.
Jacobs wrote in an email that railroad personnel responded to the spill Tuesday night and determined the fuel didn’t leak into waterways. On Wednesday, he said, the railroad crew was once again on the scene and would conduct soil remediation as needed.
Jacobs said he planned release more information about the amount of fuel that spilled and other details later Wednesday.
