Yep. Never really occurred to have Gordon S work on the wheels.

They are not quite as smooth as the original N wheels though. Ok, but a bit noisier even after some oil. Wonder if its the brass gears meshing with plastic?

Did you use drop-ins and did you find the same?

Plastic gears are usually quieter. Introducing brass gears could increase the noise.

I had the wheels in my railcar (poole) turned down and that is noisy, but it always has been.

I think this must be the case, since the wheel swap over went without issue. The 24 was particularly quiet and smooth out of the box on the N test track.

It is still well within the acceptable, I was just surprised that there should be a difference.
