Power for your layout and tools

 I live in a 100 year old farmhouse where outlets are few and far between. My wife finally let me convert the old living room into a train room. 

I got tired of extension cords.

I ran a 12/2 romex with ground around the face of my layout with duplex outlets about every 6 feet. The outlets are mounted on the bottom of the table with the sockets facing the floor so when I plug something into them the wires don't stick out in the aisle. I wired them all in series and put a 15 amp wall switch at one end.   The switch is wired to a heavy 3 prong plug that plugs into a wall socket.

My wiring is heavy enough to run tools from any outlet,  and when I leave the room I flip the switch and the trains and lights and anything else connected to the line is turned off.
