Beautiful engine. Great sounds. Runs smoothly. Negotiates all my track well.
Minor complaints: that stutter chuff, which my 3rd Rail Y6b also has; the engine slips out here and there on grades pulling around 13 freight cars; not great slow speed operation in TMCC mode, better in Cab1 mode; and a possible minor TMCC issue here and there on my layout. Need some ground planes I guess.
I'm happy with it so far.
