For some background see the January 1st post "Mocking Up Adena Wye" which explains the function and planning for this area.
This is a really deep scene, much deeper than you might typically find on many of the multilevel "shelf style" layouts I follow in the model railroading press. As you can see in the photo below, the section of wye track in the front spans over 6 feet from the NKP Caboose on the right to the lower left corner where the track rejoins the basement wall benchwork.

After spending a good amount of time brainstorming, googling ideas and browsing Tony Koester's "Designing and Building Multi-Deck Model Railroads", I found a solution.
Like others have done but in a different way, I would combine a metal track shelving system and the popular L-girder wood benchwork construction. I came across a formula from Lynn Westcott's "How to Build Model Railroad Benchwork" regarding l-girder maximum spans. I can't find the information to link it, but based on a L-girder built from a 1x3 with a 1x2 flange, I could span the 5 to 7 feet needed with minimal deflection. Weight shouldn't be a problem anyways since my roadbed and scenery material will be pink foam, it really only needs to support itself.
A few weeks ago I built the L-girders and today I finally put them into action.
First was to attach the shelf track standard for the other wall around the corner from the Adena wye, as seen below. I bought a long standard to use for the lower level in case I wanted to create another span from that location as well.
Level! |
Level again! |
Measure and double check 8 times, cut once. |
Ugly but it got the job done. |
It's just as sturdy as I had planned and somehow everything turned out pretty darn level according to the 4' bubble level!
As an even bigger plus everything still lines up with the plans.
On target! |
For this phase building the L-girder span was really getting the hard part out of the way first. Everything else should be easy following conventional shelf style layout construction.
