Because of the numerous open pit copper mines in Arizona and Mexico, I see those trucks, or at least parts of them, being moved through here quite frequently.
The bed alone is wider than a 2 lane highway and requires closure of the road while they are being moved. The route has to be carefully selected because of bridge clearances and weight restrictions. The tires are 8 feet in diameter and are moved on a separate flatbed. The main chassis requires quadruple trailers with 24 or more wheels under each one to bear the load, and they are so tall that they will not clear any Interstate overpasses or traffic signals.
A pedestrian overpass was recently removed in Tombstone, Arizona, so some of these trucks and other oversize items could be moved through town. The bridge is going to be put back into place in one month after several loads are moved through the area.
The possibility of a train hitting one of those trucks is extremely unlikely since they would never be close to a railroad except when they are being shipped to a mine in parts. They are even too big to ship by rail.
Using a Lionel or any other model train and a Tonka truck would not come close to replicating a collision between these two because of the difference in weight and bulk between the real thing and the models.
