Currently , the way physical crossings between rails are modelled(single turnouts, diamond crossings, singe or double slip switches) is very simplistic, just basically two rail templates crossing one another. It would be more accurate to model them as actual crossings/frogs. This could be done through actual 3D cells at the point of crossing and could be accompanied by guardrails around this specific point according to turnout specs. See attached example from a single turnout.
