TransLink says "human error" was the cause of Monday's (July 21) shutdown of the Millennium and Expo lines, which lasted for hours and led stranded passengers to walk along the tracks to the nearest stations.
In a news release today (July 22), the regional transportation authority states: "An experienced electrician was installing a new circuit breaker for the Evergreen Line at a power distribution panel when he accidently tripped the main breaker feeding the critical systems at SkyTrain’s operations centre, causing a system-wide shut down of train controls."
TransLink is still reviewing the incident, which "halted trains and impacted TransLink’s ability to communicate with customers over SkyTrain’s PA systems".
It was the second major SkyTrain outage in one week.
“Our trains are reliable 95% of the time, but we know that is little consolation for customers who are delayed for hours when we do have a significant breakdown,” said Doug Kelsey, TransLink's chief operating officer, in the release.
“Two major disruptions in one week is unprecedented, and the two incidents are completely unrelated.”
TransLink says it will offer a "free day of transit" on B.C. Day to "show appreciation for customers".
