It's a real head scratcher, that makes you ask: Just how did four teenagers shut down a bus and then beat the driver and passengers and rob some of them?
The CTA finally explained that an external panel door leading to a battery shut-off door was left unlocked, and the teens reached in and shut down the bus. And it turns out that "CTA policy requires bus mechanics to keep the compartment housing the battery-disconnect switch unlocked to allow easy access by firefighters in the event of an electrical fire or other emergency that would require shutting down power on a bus." That's according to a union official quoted in the Tribune story.
The upshot is that the CTA is changing policy on locking the shut-off door:
The CTA issued a reminder to all bus personnel to follow standard operating procedures and check buses to ensure the access panels are locked before taking a bus into service, CTA spokeswoman Catherine Hosinski said.
“Prior to us implementing the locks, we conferred with Chicago Fire Department officials,’’ she said. “It was decided that emergency-responders could break into the locked compartments with their fire axes.’’
I should think so.
