Morrisville Yard was an important location halfway between Philadelphia and New York along the Northeast Corridor. It's where the ex-Pennsy Trenton Cutoff connected back into the mainline between Philly and New York. Morrisville was an active yard serving a number of local industries, including US Steel's Fairless Works.

This gallery also includes photos from West Trention, just across the Delaware River (but on ex-Reading trackage).
