SEPTA not sure when service will resume

EVEN THOUGH SEPTA suspended all of its services shortly after midnight on Monday, subway cars could be heard rumbling on the Market-Frankford line in the late afternoon.

What gives?

SEPTA spokeswoman Jerri Williams said the agency was using "pilot trains" to ferry emergency personnel and search for leaks and hints of flooding underground.

SEPTA officials expected to spend about six hours Tuesday morning doing a system-wide assessment to determine when services will resume.

The Broad Street and Market-Frankford lines will likely be the first to resume full service. Other lines, like the Regional Rail, Norristown High Speed Line, and route 101 and 102 trolleys, might take longer to resume.

SEPTA said the Paoli/Thorndale; Airport; Chestnut Hill West; Cynwyd and Trenton lines would be suspended until further notice.
