A small brush fire was stopped quickly Tuesday afternoon after it was found near the Empire offramp on the parkway in Bend.
Bend Fire & Rescue said the fire was spreading along the railroad tracks adjacent to the offramp near Corporate Drive close to Lonza.
The fire spread to both sides of the tracks and was stopped at 1/4 of an acre, Bend Deputy Fire Marshal Dan Derlacki said.
BNSF stopped train traffic for a short time while Bend Fire & Rescue and Police crews worked to stop the fire from spreading.
No buildings were damaged, but Lonza did evacuate its staff from its main building out of precaution.
The cause of the fire has not been determined.
