Do all NS east-west through freights pass through Pittsburgh's Penn Station, or is there some sort of bypass between the Pittsburgh Division main line and Conway Yard? I visited PGH a few weeks ago, and noted that there are two through tracks that curve to the right over the Allegheny River Bridge towards Conway Yard. I also saw several doublestack freights run through. However, NS runs lots of through freights, and I wonder whether this routing can handle them all.
