Metro builds Web site about faulty track circuits

Metro has created a website to alert riders daily of where it is working on problems found in its track circuits.

The move is an attempt to provide some openness to the system’s safety and operations after criticism of how it has handled information related to the June 22 crash that killed nine and injured more than 70 people. But the transit agency still has not been able to say how many circuits have needed repair under new testing standards established after the crash to give a sense of how widespread the problems may be.
