WASHINGTON (CBSDC) — Metro is working to identify the source of computer glitches that shut down the rail system twice this past weekend and taking ‘mitigating steps’ in the meantime.
WMATA is exploring the possibility that shift changes may be to blame for the failures.
The failures happened at about 2:00 p.m. Saturday and 12:30 a.m. Sunday and forced trains to stay at the nearest station for a half-hour each time.
Metro spokesman Dan Stessel says once metro noticed the pattern employees were asked to stagger their log on times.
“We’re being very careful in metering people as they log on to the system in the event that has something to do with it,” Stessel says. “Now we’re not sure that it does.”
There have been no more glitches since the metering began, to Stessel’s knowledge. He says technicians have been working around the clock to monitor the system and investigate what happened.
