Turning around the corner with a big 61'6" interurban
Some may be afraid if this big cars could really negociate sharp curves. They can. I tried a 138 mm radius, about 5.5 inch. It works, and there may be always a small reserve. This is a prototypical radius of slightly under 40'.
The only adapation to be done is cutting the 4 upper corner edges of the NWSL Stanton drive with a cutting knife.
