Steep Grades on the CSX Philly Sub ? For trains departing Philadelphia, the climb west to 58th St. is brutal. Q409 is down to a walk - with the whole train on the grade.
CSXT manifest Q409 rolls east on the Harrisburg Subdivision track which leads to the high line. Train is led by former Conrail SD60i and snakes under both sets of signal bridges at Belmont.
