I don't bother to cut the rails past the frog, unless the customer specifically asks. I do advise them to use insulated rail joiners at least on the inside rail or they will have a short like previously mentioned. My feeling is that I or he will power the frog anyway, the extra length isn't going to hurt anything, and the gaps are well within the accident contact area anyway. Other supporting evidence suggests that the turnout is stronger because there isn't any gaps in the two inner rails, so the turnout is stronger along its "axis"
Works well with crossover also that way all you do is place one set of plastic joiners between the two turnout frogs, and you don't have to run a separate feeder to each separate track section.
