How to scratch build model railroad signal lights either kit bashing or starting with basic materials. Covered also is information about setting up  a signal light control system on your model railroad using two different Arduino programs.   Using an Arduino to control your signals is cheap compared to the expense of commercial systems.

 

Here are some pictures of prototypes.

As we build out this page, we will first provide a link to some excellent material.

And then to control those lights, here is another link.
