Full service is running on both O-Train lines, after a brief interruption on the north-south Trillium Line.
O-Train service was briefly interrupted, with riders reporting R2 replacement buses being put into service between Greenboro and Bayview stations, early Friday morning.
OC Transpo said the outage was caused by a stopped train but did not provide a reason for the stoppage. It says full service was restored by 6:12 a.m.
A full complement of 13 trains were lauched on the east-west Confederation Line, Friday morning, according to transit officials. That meant a train approximately every four minutes.
Supplemental bus service was scheduled between Blair, Hurdman and Tunney's Pasture stations and the downtown, in the morning and afternoon.
