Operational One-Line Wall Art

A Mapboard, Rebuilt in Brick

I started my career in a system operations center, in front of a tile mapboard that carried every transmission one-line we dispatched. When that center was retired I managed to snag a section of the board. It hangs in my office now, and for years I couldn't look at it without feeling I could rebuild the whole thing out of brick. This piece is that feeling, finished: a working one-line rendered in LEGO, made to hang on a wall the way the original did.

A few notes from the bench, none of them really related to each other. It was designed to be lit, with clear tiles for the breakers and channels run behind the panel. The transformer structures were the hardest part to get right; they don't want to sit flat against the field without bowing. It's heavy, the way brick on a wall is and a print isn't. And it isn't fixed to this one grid, so any substation one-line could be built the same way.

The Board at Central Dispatch

For the better part of a century the transmission grid was watched from a single wall. The mapboard at the System Operations Center was a floor-to-ceiling tile schematic of every line and station BEPCO carried. It was where dispatchers read the state of the system at a glance, and it stood until the contemporary era retired it in favor of screens. When the board came down, the Records Office held back one panel rather than scrap it; what is rendered here is that panel's one-line, preserved in relief so the schematic a generation of operators worked from was not lost to the upgrade that replaced it. It is filed as a one-of-one. The board itself is gone; this is the record that outlived it.

"Effective this date, the mapboard is retired from active service. Monitoring of all transmission facilities transfers to the operations consoles."
