Is that the ‘nondetonation nanodiamond’ Nano-lube? There is a range of pressure where that stuff works best and I’m not sure where the ‘optimal’ size range of length of the brass… well, bearing brass in contact with axle journal surface… would be.
I’d think anything that would ‘wet’ brass bushings and stay reasonably in place eould produce some effect of viscous drag – again, that’s not necessarily bad but I’d bet the result is gliding more than free rolling as with the conical point contact…
I dont know if this was mentioned yet, but I was considering just enlarging the Bachmann plastic truck sides, and place inside roller bearing wheels (by Rapido) in, once they’re released (hopefully as parts for their new Bombardier cars):
They seem to be fairly freerolling, atleast in the video, and should ve very easy to install.

How much of a “rivet counter” are you?
Easiest fix if you do not count rivets, replace trucks with “standard” passenger trucks from other models. Then you can use the standard needlepoint axles which are more free rolling.
If you need “prototypical accurate” inside bearing trucks, then you will be much more involved, and I personally have not done this. I will therefore defer to those who have.
More power on the head end. (There’s a reason those old Walthers Mainline F40PHs are so heavy.)
