Check the dimensions of the wheels and tires being installed. The train wheels being installed are identified as being 4' in diameter. They are about 3' in diameter at the most. The rubber-tired wheels are identified as being 6-1/2' in diameter. They are at the most 4' in diameter. Not being picky, just an old carpenter and welder who is used to visually estimating the sizes of things compared to known sizes of other things in the area.
Excellent show.
