Don't know Nomad, no one has reported hitting anything that could have been a person! Sometimes, especially late at night or early morning, it's possible for drivers to think they have hit a deer or something. There was one case not so long ago when a driver hit something, inspected the front of his train when he stopped and found no indication of having hit anything then a body was found on the tracks half hour later. Although, this can't have been the case with this one, there would have been mess on the train, if not on the front then underneath. So without any witnesses it's hard to say whether it was suicide or accident
