I'm working on a model of the Garabit Viaduct for the train. As you can
see I have a lot of it done. Okay, so some of the auto-positioning math
for the crossbars is sloppy, but hopefully it's good enough for my
purposes. By making a bridge, I can avoid having to do detailed enough
landscape for immediate foreground view.

What I'm wondering is how the top platform is constructed on such a
bridge. There is basically one long rectangular box with the x-shaped
braces, but there must be something on top of that because I don't think
they would just have rails over a wireframe box with a 400 foot drop
underneath. It'd be much appreciated.

Questions / comments?
