The talks between the unions and SEPTA has ceased until a state mediator will get involved.  As result of the strike over 400,000 people in the area has no choice but to choose other means of transportation such as car pooling; while others took the Rgional Rail lines. Let's hope this strike will get resolved as soon as possible.
Here is the page off of SEPTA's website that shows the services running during this  strike.

Pressure from Governor Ed Rendell and other elected officials has yielded a tentative agreement for both UTU 1594 and TWU 234 members. The agreement was announced by Rendell yesterday around 5:30AM. Around that time some transit service began to run. The MFSE and BSL began limited 15 minute local service around 6:45 AM. By the afternoon rush hour all rail service was back on line and all bus routes were up and running however there were many missing trips. One report states that Neoplan 40 footers were not used yesterday because they had so much trouble starting them up. Details of the contract agreement released yesterday state that it is a 4 year contract with 3% raises each year and all employees will pay 1% of their salary towards healthcare. The only reason union members agreed to pay healthcare was because management will also now pay for their healthcare. Had management not agreed to that this strike would be prolonged. Today (Tuesday) all service was running at or near normal levels and the number of missed trips went back to that of an average weekday.
