SEPTA says it expects significant service disruptions to continue into Monday following this weekend's winter storm.

PHILADELPHIA (WPHL) — After suspending bus, Regional Rail, and Metro Routes T & G service at 2 p.m. on Sunday, SEPTA announced it will gradually restore service on Monday, as conditions allow. According to SEPTA,

The Southeastern Pennsylvania Transportation Authority will halt all Regional Rail and bus operations, and the G1 Metro trolley line, as of 2 p.m. today (Sunday, Jan. 25) because of extreme weather, the agency has announced.

After more than 9 inches of snow fell in Philadelphia on Sunday, the region will need some time to get back to normal. SEPTA, New Jersey Transit and Philadelphia International Airport will be open Monday, officials say, but customers may still face cancellations, delays and disruptions as they ramp up to normal operations.

The agency announced that all bus and Regional Rail service will be halted beginning at 2 p.m. Sunday, with service remaining suspended for the rest of the day. SEPTA said operations will not resume until conditions are deemed safe for both passengers and employees.

The Market-Frankford and Broad Street lines will be most reliable during the weekend snowstorm, officials say.

SEPTA‘s Regional Rail express trains are set to return to regularly scheduled service on Monday after several months of significant disruptions due to federally mandated inspections. Riders of the Regional Rail system have been dealing cancelations,
