A squirrel fell onto an electrical line yesterday and the subsequent power failure stalled SEPTA's commuter rail service for more than 30 minutes during rush hour, delaying about 30,000 commuters.
SEPTA officials said the falling squirrel caused a power transformer in an Amtrak substation in the Powelton Yard near 30th Street Station to fail at 4:54 p.m., cutting off overhead electrical power to the rail systems.
SEPTA spokesman David Murdock said for about 30 minutes, all eight regional rail lines "were stopped cold." This was "enough to destroy the entire schedule and throw everything out of whack," he said.
