Model Railroad Hobbyist | January 2016 | #71 DCC IMPULSES column Bruce Petrarca Econami DCC + sound installation into an O-scale Weaver RS3 This month, I’ve decided to merge a review of the SoundTraxx Econami 4-amp (ECO-400) diesel decoder with an O scale installation example. While this is O scale, there are some hints and tips along the way that work in all scales. This loco belongs to a friend. I operate on his O and On30 layout once a quarter or so. His On30 operators are having so much fun with wireless DCC and sound that he decided to convert his standard gauge to DCC by adding a booster and enhancing some of his wiring. He needs a DCC loco for the job. Since this loco [1] has been his workhorse, what better place to start than here? Before jumping into this installation, I recommend you review my first few columns, starting in October 2011 (mrhmag. com/magazine/mrh-2011-10-oct/dcc_impulses).
