Ron,
How did you ramp up the code 55 rail for the pick up roller to cross the closure rails? I'm building switches with a Fasttracks jig and am at the stage to add the center rail. I started on a project similar to this a couple years ago but a change of address put that on hold. Now that I am moved I'm finally at the track laying stage and am using all code 148 track with code 55 center rail.
