Beyond the cancellations that SEPTA riders have been faced with since the start of the week, on Thursday morning commuters across the city saw additional delays as “signal issues” led to a slowdown across its SEPTA’s Regional Rail system.

The mass transit provider posted about the issues on social media at about 5:13 a.m. on Thursday.

Officials also said that riders should “expect delays of up to 30 minutes as we address signal issues affecting service in the Center City area.”
