This is a DCC safety wiring connection.
Even though this is an example of a DCC two rail system, it can be easily changed to any three rail track system.
From the permanent mounted hinged side, it will require two flexible track feeder wires.
These two wires are permanently mounted to the lift up bridge or swing out bridge, directly to the main track power.
A micro switch is used to insure that the lift up bridge or swing out track layout section is correctly positioned.
The one problem with this type of wiring, is connecting the two required wires the opposite side, safe section.
Required to run two wires over (or under) this open aisle section.
Why not totally replace these two required wires connections, with a different procedure?
Why not add two flexible electrical track contacts from the lift up bridge or swing out track layout section track power,
directly to the opposite side, safe section?
