GO Transit says it was a lightning strike that caused major delays west of Union Station on the Lakeshore East and West lines on Monday afternoon.
For over two hours during rush hour, no trains were running westbound from Union Station.
Trains began running again at 8:13 from Union Station, but residual delays were still expected.
Sunyya Kukaswadia, a Metrolinx spokesperson, says the cancellation out of Union Station also caused residual delays on the Lakeshore East line.
Shuttle buses were not running during the delays due to the sheer number of the impacted passengers. GO Transit officials say it was close to 10,000 people.
Riders have taken to Twitter to express their frustration over the long delays and reportedly extremely hot trains.
Almost 90 minutes- no water standing room only and 95 degrees. And no communication at all. Someone just hit the emergency alarm. I think someone passed out on coach 2055 @gotransit @gotrain @torontostar @cbcnews @citynews

Have been stuck on the Go Train, standing, for 1.5 hours when my back started driving me nuts. A woman seated next to me could tell & stood to give me her seat while the three other dudes in the quad of seats looked the other way. Yet another reason why I love women.

I have been on a train for 2 hours. By any measure, leaving Toronto I should be in London or half way to Montreal. Wait, I’m on a @GOtransit train so I’m three stops from Union. So much for a 30 minute delay. I think you meant 110 minute delay #epicfail

Kukaswadia added she understood riders were frustrated during the lengthy delay.
“We know it was incredibly frustrating. The weather was not great. We apologize truly for the inconvenience,” she said. “We tried our best to get everyone moving as quickly as possible after the lighting strike impacted our service, but we really do appreciate our customers patience and we have been listening.”
Officials are encouraging riders affected by the delays to file a claim on their Service Guarantee page starting Tuesday morning so they system has time to process the information.
