The reason I doubted the story was because of the way the bridge was on fire. The whole damn thing was enfulged.. I was failing to see how that would happen based on the story.

But the tressle would have been built with wood that is soaked in creosote, probably coal tar creosote actually. Which is pretty easy to set on fire. And since creosote is on the outside of the wood, it would have spread very rapidly across the span

Yip my dad was a salesman for 43 years for Koppers Inc. who is the leading supplier for the RR companies for treated wood. They still treat the wood at the Denver Plant.

Thats crazy. I never would have imagine wooden bridges would exist for a train. Wood seems too fragile for such a task.

There are tons, and wood is actually a pretty strong material. Ever seen trees pwning cars?

With that said, steel pwns wood, methinks, for bridges at least.
 
That was truly amazing. I'm reading the article, about to call shens, and then I saw the images. Man, they are simply incredible.

its possible im wrong, but that may not be strictly so....

from what i remember the steel used in bridges like that is actually softer steel, allowing it to give way a fraction, if the steels too hard it fractures from the pressure of the trains going over.......so if its softer steel, the heat from that train and the coal catching fire could well be enuff to soften it and cause it to bend to much and still topple the train...

like i say i could be wrong, so dont flame (scuse the story based pun..heh) me, just something i vaguely remember being told.....
