RTR12, substituting O-54s for O-72s didn't really do much, but it did give me the idea of re-configuring the leads using O-54 curves off the turnouts and I was able to come up with this. It will require a little modification of the peninsula, but I think it will be worth it and I actually got a slightly large yard too, so thanks for commenting. If it were my layout, I'd still add a LH turnout to the left most end of the top yard track to run directly to the TT.
