This was a horrific accident and this tragedy has affected the whole community.
It has been mentioned in previous posts that "someone" waved the truck on through. I have not read this anywhere. There was, however, a policeman in his vehicle, behind the truck, as were other friends and family that were following the truck/float to the end destination.
From my understanding, all the Veterans in the parade were injured Vets and were being honored with a banquet and a trip to go hunting. Several of the Veterans were in wheelchairs and they were placed at the back of the float, sitting next to their wives.
There are no curves, trees, obstacles to interfere with the sight of an oncoming train at this location. It is flat land as far as the eye can see.
There is a slight incline when approaching the actual train tracks. This intersection is a heavy use intersection. You will notice it also has traffic lights as well.
Trains are not allowed to blow their horns in town anymore because a local, downtown hotel complained about the noise.
Trains are allowed to travel 70 mph through town. Cars, however, are allowed to go 40 mph, on the street adjacent to the track.
