Metrolinx slowly resumes GO, UP transit service amid CN network-wide system failure

Metrolinx is slowly resuming GO train services following a CN network-wide system failure affecting all GO and UP Express rail corridors Tuesday afternoon.

In a statement to Global News, CN calls the outage, “an internet connectivity issue.”

“GO trains, VIA trains in and out of Union station, as well as CN’s customer service portal, all of which require an internet connection to CN’s servers, are currently impacted,” reads the statement.

However, the rail service says that CN trains, Amtrak trains and Montreal’s EXO trains are currently operating.

Currently, Metrolinx is prioritizing moving customers from Toronto’s Union Station with outbound trains, including UP Express trains to Pearson airport starting to run every 30 minutes.

Customers travelling into Union Station Tuesday evening should expect less frequent service, with trains running every 30-60 minutes, the agency says.

At the onset of the outage, around 1 p.m., Metrolinx said all GO trains were being held at the nearest stations while crews worked to resolve the issue. Shortly after 3 p.m., limited service returned to the UP Express and designated GO Transit lines.

However, Metrolinx continues to encourage customers to look for other options amid the outage.

“Trains are expected to be very busy, so please continue to explore alternative ways to get to your destination this evening – or consider travelling later this evening when trains and buses are expected to be less busy,” a statement from Metrolinx reads.

While there is no indication of a cybersecurity issue, per CN, the cause of the outage is being investigated.

In the meantime, the TTC has added additional trains to Line 1 and 2 as well as extra buses at key stations to assist with the delays.
