SkyTrain service in Vancouver was disrupted Wednesday morning by a computer glitch.

Trains on the Expo and Millennium lines were held at stations about 11 a.m., due to "computer issues," transit officials say.

Service resumed just before noon, but continued delays are expected while the backlog of passengers is cleared.

Operators drove the trains manually until the computer system could be fixed.
