开云体育My first sound locomotive was an Atlas loco with a QSI decoder. ?It was followed by two more Atlas locos with the QSI decoders. ?They had great sound and I loved them until they kept providing maintenance issues. ?Eventually it boiled down to as soon as the loco wheels became a little dirty, they started shutting down, and other strange behaviors that always required reprogramming (after cleaning the wheels). Interestingly just so you know, I do run a clean railroad :-) but these locos were always the first to show wheel dirt which was actually not grime, but just dark spots on the treads which were easily cleaned. ?Other locos with Soundtraxx Tsunami decoders just kept running while the QSI protested. ?When Soundtraxx offered a decoder exchange I jumped on the opportunity and replaced the QSI with Tsunami 2’s. ?Those Atlas locos still sound great, but the need for the QSI maintenance plan is no longer needed. ?Interestingly one of my operators has a P2K loco (GP30) with a QSI decoder and we NEVER have a problem with it. ?And by the way it has the best horn of any loco on the layout. ?You can do long and short horn with the horn button alone. I just thought I would add my QSI experience to the discussion because it was a major factor to operation, until they were replaced. ?? Thomas Cain Indianapolis, IN atsf93@...
