D500 posted:I certainly would not do anything to disconnect half the drivers for so marginal an effect. I get it, and I would have been on your side back in the day, but, after operating articulateds for 30 years, I found out long ago that this "synch" problem just does not visually exist for me at scale road speeds (and I don't mean 60 smph+ - I mean typical and accurate road speeds).
I was watching a modern video (the UP excursion Challenger) the other day (with actual sound, of course), and the out-of-synch rods and even sound were fleeting and hard to see above yard speeds - and sometimes weren't even there, of course.
My complaint is out-of-synch model compound articulated (the "Mallets") sound, which never went out of synch in the exhaust because only the 2 low-pressure cylinders exhausted to the atmosphere.
I have hours of sound recordings of "simple" articulated N&W Class A that are in synch for as long as you can hear it. Also, recordings of when the "compound" Y6 class locos are "simpled". It does not take very long for both of its engines to synch up.
Watching several of the Big Boy videos, it did the same thing.
