Repost from The Benicia Herald
[Editor: Question: was the petcoke dust in these cars open to the wind when they derailed here in Benicia last Saturday? What happens to the petcoke when one of these cars jostles up and then bangs down off the rails? Anyone have a photo? ANSWER TO THESE QUESTIONS FROM A LOCAL OBSERVER: “The cars that Valero uses to transport petcoke are ‘Hopper Cars’. They are closed top. They are not open gondala cars. No, the product was not open to the wind. They are completely covered and have a top fill with a door and 3 or 4 bottom discharge slide gates.” – RS]
2 UP trains [sic] derail near Benicia refinery; no injuries or spillsMay 19, 2014, The Benicia Herald
Two Union Pacific train cars came off the rails about 5:25 p.m. Saturday, Mark Davis, UP director of corporate relations and media, said Monday.
The train serves Valero Benicia Refinery, Davis said. The derailment happened near there.
“There was no petroleum coke spill,” said Sue Fisher Jones, the refinery’s public affairs manager.
Davis concurred. “There were no injuries or spills,” he said.
“Both hopper cars were loaded with coke and derailed upright with all wheels off the rail,” he said, describing the incident.
“The cars were placed back on the track Sunday morning, and the cause of the derailment is under investigation,” Davis said.
