Mark Rollins – Model Railroading – model railroad information, complete with model railroad circuit diagrams. Electrical Circuits you can make! With 3D wiring Sketches, easy for the beginner.
I enjoy model railroading – HO scale thank you. I build modules that vary in width anywhere from 1 foot to 3 feet, with lengths ranging from 3 feet to 8 feet. Each module has a separate setting (even different decades). I have completed a switching yard, a small industrial park, and a farm scene.
A dual alternating flashing light circuit. This project is best for mounting on a layout to light a crossing or ring a bell.
