Missing CFL lamps from old layout were found and installed to complete lower level lighting. An adjustment may be required over Florence Yard as the upper level valence is so far back that little light is coming from that for the yard. Most structures have been placed and several with damage have been repaired. Trains have been run over all main and staging tracks with no electrical, derailment, or clearance issues. Proper detection is suspect at this point; BDLs seem subject to considerable false detection despite adding sensistivity adjusting pots.
