Do any of you have experience yet with the most recently released Lionel American Flyer 2-8-4 Berkshires. I believe they have 6-4402X product numbers depending on the railroad they're painted in (0=NKP, 4=Erie, etc.). How well do they 1) operate - motor control, smoke, sound, run forward and reverse, etc. 2) any issues/failures, 3) work and/or look compared to earlier release Berks, 4) what's the Bluetooth app like? Thanks.
One other questions - does it matter whether a Flyer Chief engine such as these is put on tracks that have a TMCC or Legacy Command base connected to the rails and powered up as well as a transformer? Are FC engine oblivious to the presence of a Command base (i.e. don't detect it or care as long as there is either AC or DC going to the tracks - 18V if in Remote mode, variable if not)? Or can the presence of a Command base interfere with proper FC operation?
