An issue with overhead lines around 6:00 A.M. halted the CTrain system in the core area.
As a result, authorities told riders to expect significant delays in getting to their destination.
Calgary Transit dispatched more than 20 shuttle buses to various locations to pick up passengers, but some people had to wait over two hours to get a ride.
Officials said each train carries about 600 passengers, while an articulated bus can carry roughly 90.
There was no immediate word from Transit on the cause of the disruption. (CFFR, CHQR)
