The TTC has restored full service on the Yonge-University-Spadina subway line after radio problems caused delays during Friday's morning commute.
The TTC reported that full service was restored just before 8 a.m.
Earlier in the day, the TTC ran shuttle buses along the route as the radio system that allows train operators to communicate with transit control went down. That forced the TTC to go to a backup system, which slowed the rate at which trains could depart the yard.
Reporting from the Davisville subway station on Friday morning, CBC's Trevor Dunn said shuttle buses were running along Yonge Street but added that most passengers had opted to stay inside the station and wait for a train.
REPEAT: Full service has now been restored on the YUS line. Things may still be busier than usual at subway stations.— Joan Chang (@cbcjoanchang) August 16, 2013
