Those piers have been sitting unused for about a hundred years, and if they somehow were useable they'd need serious scour protection if anything heavier than a loaded wheelbarrow were to be put across any bridge using them as footings.
The other issue is yardley station, which would need a complete rebuild to make room for extra track. the bridge there would need to be re-configured too, as there is also a ped passageway. Also, not sure how you'd wire it all up or the exact profile of the route.
The other thing, is that a freight would have to cross 2 tracks to get to the yard at woodbourne, or to get to the turn-off by neshaminy, so you'd probably see freights use the northern of the 2 current tracks, leaving septa with the 2 outside tracks.... that would take care of high platform issues...
