Sam,
Here's what I did. The loco still runs well. It's not as quiet as when new. I use the 44-tonner to test trackwork and to display in the yard.
The gears are still working... so far.
Regards,
Jonathan

Now that I'm getting up there in years, my layout will be 48" high so I can scoot under the layout on a shop stool, for wiring and the like.
