I would dearly love to have good, remote operating turnouts for EZ-Street, but I have planned my layout without them for the time being. I suspect it will be a while before Bachmann starts offering them: that they will most likely concentrate on re-issuing the other vehicles and filling in the product line with easier stuff to develop first.
I cheat now, because I do have switches on my SS. On the left in the picture below the road sections you see just inside the tunnel entrance are Lionel transition pieces (SS to O-27 tubular track) - as O-27 track, the loop does a full turn to come back the other way out of the tunnel, in the other lane - all under the scenery. However, just inside the tunnel there is a Lionelturbular track switch that goes off to several others to create a three-siding "18-wheeler" switchyard where I can park three vehciles (I lean down and look through the tunnel entrance to see them, if and when I operate them). I plan to use switches under the scenaery to similarly connect two loops I am builting now.
