Philadelphia ? Subways, trolleys and buses started rolling again for the first time in a week Monday after city transit workers agreed to end a strike that forced more than 400,000 daily riders to find some other way to get around.

After an all-night bargaining session, the Southeastern Pennsylvania Transportation Authority reached a tentative agreement on a new contract with 5,300 union employees. The main issue was how much they would have to contribute to health care.

Subways, trolleys and a few bus lines were up and running by 7 a.m., and full service was expected by the afternoon rush hour. The four-year pact must still be ratified by the workers, and a vote was expected within a week.
