Thanks for looking into this! I checked Barry's book because I recalled that the transformer needs to be set to 22 volts for the Variable channels in order to have the track voltage match what you see on the remote. However, I am using the fixed channels. I did not see anything regarding fixed channels having a discrepancy. The Z-4000 is putting out exactly what my meter says on the track. So there is not a voltage drop going from the transformer to the track. Just curious why the engine's track voltage soft key indicator would be showing less voltage on all engines - and would that be why it seems like the BigBoy needs a little extra juice (or maybe it's because the thing weighs as much as a small car).
MTH engines are rated to go up to 22 volts, so I just run the BigBoy at 19-20 volts and it eliminated any problem of slowing down around the curve or "skipping a chuff" intermittently.
Anyone have any additional thoughts - please chime in.
Thanks again!
