The Broad Ridge spur still operates.
Here is the schedule for the Broad St. Line:

The schedule says "Local Trains operate every 8 Minutes until 6:30, and then 10-12 minutes after. Then a night bus that run every 10-15 until the subway opens.
For me, when I visited Philly last year, was that SEPTA operated fairly well, but was lacking something. I just cannot put my finger on it, though. I am not a fan of the fare structure, either.
