SEPTA Regional Rail Lines are operating on or close to schedule, officials said.

Earlier today Regional Rail riders were subjected to delays due to heavy passenger traffic.

Amtrak signal and power problems were also affecting the Wilmington/Newark, Trenton, and Chestnut Hill West lines, but those issues were resolved earlier Sunday, SEPTA said.

Commuters are advised to check SEPTA's website for the latest system status information.
