Williams locomotives have more lateral play in the drivers than most other 2 rail models. I doubt the flanges will be the issue on your Williams locomotive as they typically build in a fair amount of lateral play in their models. Commonly with 4-wheel trailing trucks the limiting factor negotiating tight curves occurs if the insulated rear trailing truck wheel (left side) makes contact with the frame creating a short. The 2 rail Williams model used the same "high rise" frame as on their 3 rail brothers giving the trailing truck a wide swing. Another potential limiting factors is with the leading truck making contact with the cylinders. To mitigate that manufactures who offer the same model in 3 and 2 rail often slightly stretch the leading truck wheelbase, or use smaller diameter wheels, or do both. The best way to know for sure what your locomotive can handle is to tack down 2 pieces of 2 rail flex track on a sheet of plywood (or Homosote) to a variety of radii and see what your locomotive can handle.
