I read on the computer (don’t remember which screen) that the BNSF had a rear end collision between two freight trains in Tulsa. In viewing the TV clip, the first train was a vehicle train. The comment by the BNSF public information person in the area said that a coupling was vandalized causing the derailment. Of course, that does not make any sense.
The Tulsa CBS station does have any information on this derailment.
