I took a quadruple track, changed the track mesh to JR DK Grey, and adjusted the spacing to PRR specs, and set the track directions to 0,0,1,1 (or something like that to make 2 go one way and 2 go the other way) and it works fine for me. It is much simpler to do than adjusting multiple tracks. I like PRR-style stuff, so I'm going to use it.
