GO Transit trains not running in southern Ontario due to signal problems

GO Transit trains are stopped and holding at their stations due to a network system failure, Metrolinx says.

In a post on X, formerly Twitter, GO Transit said the problem is tied to a network-wide Canadian National Railway (CN) system failure that is affecting all rail corridors.

"Trains will continue to hold at the nearest stations," the post reads.

"Our teams are work with CN to resolve the issue quickly and safely. We will provide an update when more information becomes available."

CN's website also appeared to be offline Tuesday afternoon.

A Metrolinx spokesperson told CBC News that two GO Trains are stuck between stations, but passengers are being transported to nearby stations.

All passengers are being advised to take alternative transportation options, the spokesperson said.

In its own post on X, VIA Rail said trains entering or leaving Union Station will experience delays, and asked passengers to visit its website for updates on their trips.

Pearson airport also issued a statement Tuesday afternoon, saying it is "closely monitoring" the situation, as it has halted UP Express trains to the airport.

"There is currently no impact to our operations, but passengers may need to find an alternative way to get to the airport," the statement reads.

There is currently no estimated time for when operations will resume.
