"In my 38-year career, I don't recall a situation like this," BSNF spokesman Gus Melonas told KOMO Newsradio.
He said the lead locomotive was hit 15 times by shots fired from a car that followed the train on the night of Sept. 24. The engineer and conductor on the train were not hurt.
"All of a sudden they could hear rounds and feel rounds striking the side of the locomotive below the window of the operating cab of the lead locomotive," Melonas said.
He said the train was hauling freight containers at 25 mph from Chicago to Seattle when the shootings took place. Shots were fired from three locations as the car followed along after the train.
The first shots were fired at about 8:30 p.m. from a crossing at Bear Springs Road, and struck the side of the locomotive on the engineer's side of the train.
Minutes later there were more shots fired from the car at a gravel road near a grain elevator, which struck the locomotive on the conductor's side. A third volley of bullets hit the engineer's side of the locomotive as the train neared Highway 28, Melonas said.
A total of 15 bullet holes were found in the locomotive when it pulled into Wenatchee - 13 on engineer's side and two on the conductor's side.
The two crew members did not get a good look at the car because it was after dark and they were focused on operating the train. They described it as a dark sedan with roundish oval headlamps, with a square backup light in the rear window.
The railroad is working with investigators from the Grant and Douglas County sheriff's offices and the Washington State Patrol to solve the case.
Anyone with information is asked to call 1-800-832-5452. A $5,000 reward is being offered for information leading to the arrest and conviction of the shooter or shooters.
