RENO, Nev. (AP) - Lawyers for a trucking company are accusing two railroad companies of tampering with evidence about a June 2011 collision between a tractor-trailer and an Amtrak train that killed six people in northern Nevada.
Lawyers for John Davis Trucking Co. say they have evidence the companies tampered with a video of the crash and are hiding or have destroyed the crossing gate arm.
The Reno Gazette-Journal reports the lawyers claim video from the train's camera was altered to make it look like the gate was working and say the gate arm has vanished.
Union Pacific strongly denies the allegations and says it plans to vigorously defend itself in state and federal courts.
Amtrak declined to comment.
In 2012, the National Transportation Safety Board concluded an inattentive John Davis trucker driving a tractor-trailer with faulty brakes was the probable cause of the collision with the Amtrak train about 50 miles east of Reno.
Board members also ruled out the possibility the crossing guard gate or warning lights malfunctioned.
The truck driver was killed along with the train's conductor and four passengers
