Tuesday’s massive rail disruption had been caused by a system upgrade, according to CN Rail.
“At this time, our teams have determined that this was caused by an internal systems upgrade, which affected CN’s ability to connect to the internet,” spokesman Jonathan Abecassis said in an interview with Canadian Press.
“There’s no indication of a cybersecurity incident whatsoever. At no time was the safety of the public compromised, and at no time was data impacted.”
The digital blackout also barred Metrolinx from connecting to CN servers. GO Transit trains run partly on CN-owned tracks, Canadian Press said.
Some shorter trains. delay
Meanwhile, Lakeshore East Train reported that the GO train service was back to normal though with a couple of shorter trains and a delayed one.
“The Durham College Oshawa GO 13:40 – Union Station 14:42 train will be a couple of coaches shorter than normal today [October 4] because of yesterday’s network wide signal outage,” it said.
“You may have to board your train at a different area on the platform. We apologize for the inconvenience,” it added.
It said the Union Station 12:20 – Durham College Oshawa GO 13:22 train was also a couple of coaches shorter, while the Durham College Oshawa GO 10:10 – Union Station 11:12 train was delayed 14 minutes from Rouge Hill GO as the train needed to be repositioned on the platform.
