Much to my delight I've got everything but the Warren Truss Bridges (I don't really care for them and might sub them for some plate girder bridges instead). All the curves and switches required are in the box and I think there's enough scraps of flex track to do the straights. The switches are hideous, they have a giant manual switch machine attached but I have an idea in my head about chopping that thing off and adding a spring like this:
There are also enough scraps of pink foam in the garage to be able to stick a 28"x80" piece together. Now on the lookout for discount door...
