FDDM 411 GE 70 Ton

Starting the railroad season off with a quick (and dirty) project. I need Diesel for the Kate Shelley Division fall swap meet contest. Needing an engine for shoving cars under the loader at the elevator, I took this opportunity to build a Fort Dodge, Des Moines, and Southern GE 70T. Bachmann makes a superb little engine with DCC that is pretty inexpensive. It also comes from Bachmann in the GE orange and cream paint scheme that some of the FDDM units used making this a simple decal and dirt job. Decals were printed myself on Testors paper. I also added a teeny (non functional) beacon and a radio antenna.The final plan is to install a sound bug in the elevator with a good size speaker rather than try to cram sound inside the shell.

Cutting T-Trak Boxes

Here are some dimensions used for a few of the modules. The big quad I have planned and the two singles that are already done are standard widths and depths. Shown in the picture is an inside corner that is also pretty standard as is the double.Also in the drawing is the proposed modification to my end caps, knocking the corners off. I have no idea how you'd scenic those corners so I just eliminated them.

The real variance from typical T-Trak specs are the polygons for the s curve and the s curve with a couple of spur extensions. These ought to be a real challenge to get glued up...

To make the boxes I'm ripping 1/4" sanded plywood into 2 1/4" strips. This will allow a 2" piece of foam to slip in and have 1/4" of clearance for wires and the mounting pads for feet. I screwed up several cuts, but all modules on the proposed arrangement were cut from two 2'x4' panels.
