Oh my a look at this crash scene one would have thought that trucker was really hurt bad?
Yes I do agree with you Cerberus_Kelpie 9:40 am should have been light enough to see that big choo choo chugging down the tracks.
Unless it was very foggy,or could be even if it wasn't foggy,perhaps this trucker was sleepy,and in a fog of his own?
I found an update with a raw video>

I see in the video that the crossing arm is upright,so this may come down to the Rail Roads fault for a gate malfunction.
