10-foot Bridge SuccessWritten by TJ on July 15th, 2009
The bridge made it through our train show (see photo gallery)! It held up great. I was quite surprised to find that no member or cross bracking loosened noticeably. Usually, on trusses like this, a piece of cross bracing will come loose at some point due to vibrations from the trains.

I packed up the model by breaking it into four sections, and then piggybacked two section pairs together.

TexLUG’s layout consisted of three 8-foot long tables on either end of the bridge. One of our members (Matt S.) brought two 2.5-foot small truss bridges, and we used those on one side of the layout.

The bridge did endure some heavy loads. At one point, we had two very long trains on the main loop, and they managed to end up on the bridge at the same time. Both trains were longer than the bridge

Their were a few accidental human contacts, but it survived. The worse was when my 4-year old son was underneath and suddenly popped up. He buckled a section of deck with his head. I managed to press it all back together quickly before the train came back around
