          t’s the '70s again! Can you hear the Athearn “growl”
        
        
          going around your layout? How many remember the
        
        
          Athearn SD45 running on their layout with those horn
        
        
          hook couplers? Ah yes, those were the days.
        
        
          Some of us still use the Athearn product on our layouts.
        
        
          However, I can’t bring myself to buy the updated DCC version
        
        
          that starts at $134.98 MSRP. None of the RTR SD45 engines
        
        
          from Athearn/Horizon are offered with sound. Another man-
        
        
          ufacturer offers an SD45 with DCC and sound with a MRSP of
        
        
          $298.00.
        
        
          While at a train show, I found two of the older Athearn
        
        
          SD45s, one in Santa Fe pinstripe freight and the other in the
        
        
          yellow bonnet paint scheme. I bought them, came home, and
        
        
          laid out my project. Let us begin to improve the units from
        
        
          the 70s.
