Unless this track goes around the bend, the fault lies with the truck driver. If you can see a train a mile away, stop.
I have been involved on the EMS side of several vehicle train crashes. Cargo trains
A couple of large truck incidents. They are a mess for sure.
Evidence can be spread for a long ways. Found one truck engine almost 2 miles down the track.
The car one were most likely suicides’.
The Truck one were most likely “ I can make it”
But who knows the drivers where spread all over the place.
