Hi there
Why is that?
My proto 1 engines fly at the half way mark on my z1000 .
my proto 3 engines stay on the track & go slow at full speed !
What gives ? Please note I am running Conventional at this time !

Starting with Protosound 2, locomotives hold some of the track power in reserve in order for the cruise-control feature to work.
As the loco climbs grades or rounds curves, it starts to slow down. This is sensed by the onboard electronics, which increases power to the motors from that reserve in order to maintain the original speed. The opposite occurs under conditions that would cause the locomotive to speed up on the same track voltage (going downhill, train breaks in two, etc)

Proto1 is Conventional speed control with good sounds.
Proto3 is Command Control and has that reserve mentioned above even in Conventional operation. This means the motor in the engine never gets that last 3 volts or so unless it's pulling uphill.
Plus I suspect MTH is figuring out many of us don't want the trains to fly around the track, we want them to run at reasonable speeds.
For an apples-to-apples comparison try turning OFF the conventional speed control in your PS3 engine. From the manual:
