SEPTA's Regional Rail schedules change tomorrow; for the first time in recent memory, SEPTA timetables are changing at the same time as other railroad systems in the Northeast, including Amtrak and NJTransit. There are very few changes to existing schedules; in fact a grand total of 22 trains will see schedule adjustments. Only minor changes will affect riders on the R2 Marcus Hook, R3 West Trenton, R7 Trenton, R7 Chestnut Hill East, R8 Chestnut Hill West, and R8 Fox Chase. Only the changes on the R3 and R7 affect peak hour trains. Most of the other changes involve minor time adjustments. Follow the link for a detailed listing of all RRD changes.
