http://www.sacbee.com/102/story/138765.htmlA dramatic evening fire Thursday along the American River Parkway near Cal Expo destroyed a Union Pacific mainline track, sending billowing black smoke thousands of feet into the blue skies, and disrupting train traffic through the Central Valley.
The hot-burning fire, first reported at 5:41 p.m., quickly consumed about 600 feet of heavy-duty trestle timber and tracks in a secluded section of the American River Parkway, just north of the American River.
... Union Pacific officials confirmed Thursday night that the destroyed track was one of the company's main freight lines between Sacramento and points east, as well as a major passenger corridor for local commuter and long-distance trains.
... Thursday night at the scene, Sacramento Fire Department Capt. Jim Doucette said officials did not yet know the cause of the fire, although there were some early reports that a portion of the trestle had been pushed upward, as if there had been an explosion.
