PHILADELPHIA – SEPTA says riders should expect significant service disruptions heading into Monday.

Regional Rail, buses, Access Paratransit and Metro Routes T and G were all suspended Sunday afternoon. The agency says those services will start coming back online Monday as conditions allow.

When they do, Regional Rail will run on a Saturday schedule, while bus and Metro services return to a normal Monday schedule.

Lines that stayed running Sunday, including the Market‑Frankford Line, Broad Street Line, Suburban Trolleys and the Norristown High Speed Line, will still see delays, cancellations and longer travel times Monday.

SEPTA is recommending riders use the Market‑Frankford and Broad Street lines during extreme weather.
