I found the following 2 videos a couple years ago regarding repair of a steam locomotive in Germany. Not model trains, but an actual steam locomotive getting new drive wheels, tires and bearings/bushings, etc. The narration is in German but you can see from the video what is going on. Heavy duty stuff.
In the start of the first video, the center drive wheel jumps track and that is what started the process. There are other videos besides the two below on the reconditioning of 01 202 locomotive.
