HO scale track laying tested before nailing or gluing

After arranging track is the tentative plan, we should test to see if it works. Testing small sections will tell us if we've got any shorts or bad spots that just don't work. This track has soldered joints ONLY at critical spots on switches. All the rail has been cleaned with sandpaper and coated with Oxgard. All rail joiners have Oxgard. There are no feeders at all yet, so - so far so good.
