  1. Probably replacing the steel "tire" on the driving wheel.

    Heat 'em up and slip it on.

    1. its one of those cases where you have to do all the drivers at the same time so all the drivers have the same contact pressure with the track. makes one wonder what the coefficient of friction is with steel track and iron tires with 100,000lbs pressing down.

  2. Yup. That photo looks pretty recent, I'm curious to know where it was taken. A bit more detail on the process at about the 16:00 mark in this video---

  4. ahh. Heat treating so it expands then letting it cool, so it fits.
