Hi George,

Have a look at page 19 and 20 at, specifically the calculation for minimum radius of 4-wheel wagons. 

The link is to specifications for underground mining equipment in the UK. With a known curve radius you can work backward to get a maximum wheelbase to avoid flange-lifting. Note that the wagon weight does not appear to be part of the equation. There is probably some fudge factor in the equation but I wouldn't like to guess or calculate how much from first principles,
