Both these topics (RJ ands rj) have several modelers who consider the metal rail joiners to be conductive for the years to come. LOL! The metal rjs keep the rail aligned and may conduct electricity. Since the joins are severly stressed by operations, they work and when the solder cracks, they may stop conducting. Us old grey heads recommend adding small wire drops to wiring under the surface for best electrical performance for either DCC or DC operations. Lindsay
