I’ve noticed that because the Emerald Night’s two sets of driver wheels are
locked together, the engine struggles to go around corners: the outer wheels
have further to turn, so the wheels slip and the engine’s movement becomes
jerky.
Would it be sufficient to drive the engine using only one set of drivers?
How about using a differential?
Either way, would there be enough traction?

Actually, the 9V motor also had the same issue around corners, but I believe it
was not caused by the required wheel slip, but by the increased friction on the
flanges when they run at a (fairly large) angle to the rails on the corners.
This is mainly caused by the very tight radius of the LEGO track. I don’t think
either of your suggestions would make a huge difference.
But I Could Be Wrong.
