They could use transition joints to a larger weight on the approach to a turnout,s headblock or points and/or a frog so all 3 rails would be the same -or- they use shims under the inside and lighter rail's headblock/point,s switch plate and frog -or- they could just bolt the thing together with a smaller weight frog a hope for the best like they did in photo below of a dual + dual gauge turnout at the Koppers's tie plant in Salida Colorado.
It wouldn't matter as long as the top of all the rails, points proper placement and frogs are even.
