The Globe and Mail reports in its Wednesday edition that a network outage at Canadian National Railway delayed GO and Via Rail passenger trains for hours at Toronto's Union Station in Tuesday's afternoon rush hour. The Globe's Eric Atkins and Oliver Moore write that the service interruptions snarled afternoon GO Train travel across the Greater Toronto Area and left thousands of commuters scrambling to make other plans. "CN is currently experiencing an internet connectivity issue," said spokesman Jonathan Abecassis. CN owns and operates much of the rail network used by the passenger services. Mr. Abecassis said the cause of the problem is under investigation and there is no evidence it is the result of a hack. About 2-1/2 hours after announcing the stopping of the trains, GO Transit's parent agency Metrolinx said limited service had resumed, with information on departures available at the agency's website. Outbound trains were leaving Union Station about every 30 minutes, according to the agency, half as often as usual. Inbound trains would be less frequent, running every 30 to 60 minutes. The agency warned of continued cancellations and potential delays in the evening and said trains would be busy.
