The PRR-ER has a lot of switching opportunities, for both passenger and freight. It has some of the major PRR yards, such as Enola, Sunnyside, Morrisville, Waverly, just to name a few. Also has the major passenger terminals like 30th Street and NY Penn. Also includes the Jersey Central, Reading, and the Baltimore & Ohio with their yards as well. I could write an entire book on every single yard and industry that is crammed into this mammoth route.
"After you’ve done a thing the same way for two years, look it over carefully. After five years, look at it with suspicion. And after ten years, throw it away and start all over." - Alfred E. Perlman
