This is definitely one of the keys to higher pulling power. In real life you
have steel vs. steel. So your only chance for higher friction force is higher
mass on top. (Or use sand and live with higher wear on rail and wheels).
In Lego you can use higher masses or better “rubber”-rings. Too much of mass
will of course reduce the life span of your motor, which is not made for
that.
Old trains 4.5V and 12V had ribbed rails for higher friction. That in
combination with good rubber and high weight is the reason for their good
results.

Great video, Ben :) I watched it all the way through which is a bit rare for me.
An interesting test would be the new motor with the old ridged tracks (since
they are compatible). You may get really high traction.
