Griffon

Each of Griffon's trains has 12 large yellow "drive wheels," 12 of the smaller tan wheels mounted under the track as "up-stop wheels," and another 12 of the smaller tan "friction wheels" mounted laterally outside of the track.  Since these wheels normally wear out after just a few months of use, there are always spare wheels standing by to replace the 108 wheels mounted on the three trains.
