Direction on a railroad is whatever the employee timetable says it is, geography notwithstanding, and they customarily do say, "The direction from X to Y is westward," or something similar. On the PRR, ZOO to NY was east, to Washington south, and to Harrisburg west, and PC, Conrail, and Amtrak saw no reason to change. On SEPTA, Suburban Station to Wawa is south; to Chestnut Hill East, north; to Chestnut Hill West, south. (CHE and CHW are about 1/4 mile apart.) In fact, New Haven trains were westbound on the NYC to Woodlawn and eastbound beyond on the NH, without changing direction.
