Hi Paul -- Don’t forget the regauged Russian 2-10-0s where the driver centers remained at a 5’ gauge and wider tires were applied with the flange set inward to the 4’ 8-1/2” gauge of the US. This would mean that the tire width has to be at least 1-3/4” wider than the “standard”. This caused trouble with the 2-10-0 that traveled to the Illinois RR museum when it crossed a self guarding frog and the wheels climbed up and over the raised part of the frog. The 2-10-0 in Saint Louis (photo) was not measured, but you can see in the photo how far beyond the railhead the drivers extend, as opposed to the tender and lead truck wheels.
Have fun! Bill Winans --------------------------------- All: The real RRs use different wheel sizes. There is a 125 ton Shay in Shelton, WA that has 7.5" wheel width as I measured them my self! That works to be a code 117 wheel width in S. So Proto that!
