I have a play date with my son to run trains this evening. That will probably be it (though I'm getting ready to add blinking yellow lights to a Plasticville signal bridge, as well as build the Plasticville Union Station).
Also, I didn't like how the Sharpie bled into the balsa wood that makes the front plate of my uncoupler box, so I'll probably paint it with a dark acrylic paint and hunt for some 1/2" vinyl letters.
