Tracker John posted:The process of retrofitting a fully scenic-ed layout is a PITA. Looking back at the process, I might lean towards wire instead of tape, and get some gaffer's tape to affix the wire on the underside of the deck. I spent a lot of time making wire jumpers from tape to metal bridges and then screwing the jumpers to the tape on the underside of the elevated deck. Using wire would cut that effort in half - just snake the wire through a hole in the deck and connect to the bridge. For a new construction where the elevated deck undersides are accessible before installation, tape is easy and fast. When installing the ground plane, your multimeter is your friend. A single short to the outside rails kills the effort.
Dale also pioneered another development that really helps in many of these situations.
