Life on the CTA has been a nightmare over the past few days, with the Trib reporting a bomb threat on the Purple Line during this afternoon's rush period. The incident follows a similar hoax on the Brown Line Sunday and an evacuation of the Red Line at Berwyn last Friday due to an unattended suitcase. There was also a Red Line stoppage yesterday, but it was apparently for reasons happier than potential acts of destruction: a passenger went into labor at Morse. Update: Or apparently not. As information trickles in, Kevin O'Neil has updated the post again. In contrast to the claims of one of his commenters, the Sun-Times has now reported that the Morse delay was in fact another threat, this time from an on-board passenger.
