Productive Saturday for the HO display.

Today saw a lot of work being done on the HO display, and also a couple of trains running.  Work is continuing on the turntable/roundhouse upgrade, with some of the track in the roundhouse being spiked into place.  Further scenery work was done in the area around the entrance to the Fairfield yard.  Also wiring for one of the switches leading from San Leandro into the Oakland yard was completed....
