Can anyone sort out the mess of tracks and bridges around Easton Pa?
While not 100%, I hope this is better then nothing:
The Lehigh Line swings over to ex-CNJ trackage just east of Phillipsburg and crosses the Delaware River on the ex-CNJ bridge. It then switches back over to ex-LV trackage in Easton. I believe the reasoning for this was questions regarding the integrity of the LV bridge, but this was before my time. East of Philipsburg, the Lehigh Line is all ex-LV to Oak Island.
Trains have two ways to get to E-Rail:
-Diverging off the Lehigh Line at Bound Brook and taking the ex-RDG "Port Reading Secondary" to Port Reading NJ, where they will take the ex-CNJ "Chemical Coast Secondary" north to E-Rail
-Lehigh Line to Oak Island, and then heading south on the Chemical Coast
(I'm not sure how normal daily operations are conducted, but the majority of trains probably head to Oak Island. There are some regular intermodal, ethenol, etc trains on the Port Reading though, with it used as a "safety valve" or "back door" for others when needed)
I'm sorry I can't provide much reliable information on the route between Oak Island and Croxton, as it is much more convoluted and dense.
Hope this helps.
Of course, if anyone can correct me or provide further details, please do!
