          Our club
        
        
        
          is building a set of modules for a layout
        
        
          set in the late ‘50s to early ‘60s, centering on the Pennsyl-
        
        
          vania Railroad. Toward this end, they purchased a 2-motored
        
        
          Weaver RS3 without DCC or sound. Here are some of the
        
        
          obstacles that I encountered installing the decoder. For more

          The first step was to select a decoder for the loco. A stall
        
        
          current test showed that each motor drew close to 2 amps.
        
        
          That means that, if the motors are in parallel, the decoder
        
        
          needed to handle almost 4 amps. Even in series (which was
