Arnold, So you have added orthopedic surgeon to your list of talents. 
I ran the LC Polar Express with snow on the roof last night on the newly set up Christmas layout, reduced version for this year. I bought it two years ago, and didn't get to run it much. Last year, I didn't use it as I was recovering from a knee replacement. After lubing the moving parts, it was a little stiff running, so I was doing a break in run. I'll get photographs later this month and post here and on christmas layout topics on the Forum.
