Try to find a vacuum connection point with on your power tools or have some one follow the blade, sander or router as it cuts through the plywood. The saw dust can take over real fast before you know it.
Maybe drape some painters plastic over your many racks of trains.
Some tools have optional clip on vacuum attachment ports.
I run a Delta dust collector mounted on a furniture dolly near my cutting area.
* "Vacume" is a colloquial rendition.
