Weekend Update 6/6/21

I'd suggest keeping the turnout as a right hand switch and just adjusting the alignment of the broad mainline curves to the right of the turnout on the plan.  That way, the mainline through the turnout stays on the straight route and the siding gets the diverging route.

I agree with @CRL that the prototype will sometimes put the diverging route going in the opposite direction of the preceding curve, but that's generally for reduced speed trackage and likely entering into a siding.  I'd keep the mainline through the straight side.

Note: Do as I say, not as I do, because I violated this recommended practice on my layout.

I think the best plan would be to keep the mainline straight before and through the switch, if you have room to do that.  I have had some problems with steam loco pilot trucks picking points where the mainline has a curve with a turnout in it set up for the straight path to go outside the curve.  But, if you don't have the room, then that is still better than the S curve.

Or use a curved turnout.
