PHILADELPHIA — The Southeastern Pennsylvania Transportation Authority (SEPTA) expects most of its sidelined commuter railcars to remain out of service until at least Labor Day, but officials do not expect the problems to have a major impact on the Democratic National Convention later this month, AP reports.

A week ago, the agency shut down 120 Silverliner V cars after defects were found in the suspension systems. The shortfall has resulted in many delays, standing-room-only cars and morning trains having to skip stops nearest to downtown Philadelphia after reaching maximum capacity.

SEPTA expects to add 1,700 seats Monday as transit officials close deals to lease three train sets from New Jersey Transit, the Maryland Transit Administration and Amtrak. For the full story, click here.
