R1 replacement buses will continue to run on Ottawa's light rail Confederation Line, between Tunney's Pasture and Blair stations, until further notice after a train came off the rails Sunday afternoon.
Ottawa's general manager of transportation services said in a release that the derailed train remains on the tracks and will stay there until the Transportation Safety Board completes its investigation.
John Manconi said the preliminary inspection indicated that two axles on the second car of the train derailed, but the wheels did not detach.
There is damage to both the track and the train.
The derailed train was recently returned to service after undergoing axle repairs explained Manconi, but they do not know if the axle involved in this incident is the same one that was repaired.
An update will be provided during Monday's City of Ottawa Transit Commission meeting, which gets underway at 9:30 a.m.
