Removable Bridge
Similar to the Bascule Bridge setup “brass rod run-ups” are used at either end of bridge. Brass Rod is soldered to screw/tube “hangers” mounted under top. The rod is bent as shown in the photos to connect with the “run-ups” when the bridge is put in place on the layout.

Left side of bridge installed on layout. Notice the wire bend in the “run-up” which allows the bridge rod to touch it to insure power on the bridge. Bend must be slightly up to insure pantograph does not snag.
