Here are some unique train schedules from the past.
SEPTA issued one and only one set of actual employee schedules. This set was issued when the center city commuter tunnel was first opened. Unfortunately, some services, such as West Chester and Ivy Ridge via Cynwyd had already ceased. It should be noted, however, that there was a lot more Cynwyd service than there is today. Also, notice how the Trenton service reflects some of the service that still exists today.
