OC Transpo is informing transit riders of upcoming service interruptions on Line 1 and Line 2 of the O-Train this month.

In a memo to councillors, interim general manager of Transit Services Troy Charter says there will be two partial closures and one full closure of Line 1 in August and one week of reduced service on Line 2.

Reduced east-end service on Line 1

The service changes on Line 1 are to allow for Stage 2 East Extension integration work.

Charter says Line 1 will operate between Tunney’s Pasture and Tremblay stations on Aug. 16 and 17 with R1 bus service operating between Hurdman and Blair stations both days. Work in the St. Laurent Station tunnel will also take place that weekend.

Line 1 will be offline the morning of Aug. 31, with R1 buses running between Tunney’s Pasture and Blair starting at 8 a.m. Train service will start at noon.

“Testing and commissioning work has been progressing well during the summer. This progress has allowed us to connect key systems to the existing Line 1 segment, including the closed-circuit television cameras (CCTV), remote supervisory and control system, intrusion access system and update software on all trains in the fleet,” Charter wrote. “This progress allows the training and familiarization for electric rail operators to advance, and customers and residents can expect to see more trains operating on the east alignment as a result.”

Line 2 frequency reduced in evenings

Customers will have to wait longer for a train on Line 2 in the evenings in mid-August, as work continues to install an axle bearing monitoring system near South Keys Station.

Line 2 and Line 4 service will continue during the work, but trains will only come every 24 minutes on Line 2 after 8 p.m. on Aug. 11 to 15.

These delays were initially intended to take place Aug. 4 to 8 but were rescheduled.

Line 2 trains typically run every 12 minutes.
