I set up a tuning fork test track. Just a lead a turnout and two stubs. Patrick and I switched it for an hour with our new Kato SD40-2 with a LokSound decoder. We pulled out a couple of Atlas 17,600 gal. Corn Syrup tank cars, an Atlas PressureAide hopper, a BLMA 64′ Trinity Reefer, an Exactrail 64′ Trinity Reefer, and an Athearn 50′ box car. We ran in the dark with only our blue lights on.
