Successful Test Conducted On Late Trillium Line


This is a release from the City of Ottawa. The Trillium Line was originally scheduled to open in August 2022.

This memo smacks of desperation for good news given the outcry about recent service cuts. If the city is looking for advice, and it never is, I’d confine my press releases to real news or announcements rather than perhaps fake news.

The city has not committed to a date when the train will open in 2024:

Subject / Objet Stage 2 South – Successful Operation  of Nine Trains Begins


File/N° de fichier: 48-2023 Date: November 17, 2023

This memo is to provide Mayor and Members of Council with an update regarding a recent milestone in the ongoing testing and preparations to operate the Stage 2 south O-Train extensions,  lines 2 and 4.

TransitNext, the contractor responsible for building, testing, and maintaining the system, has begun  demonstrating the ability to safely operate nine trains, the number required for revenue service, on  Line 2, between Bayview and Limebank stations, and on Line 4, between South Keys and Airport stations. This is a key milestone in the program, as it tests the integration of the control and  signaling systems, vehicles, track infrastructure, operating procedures, and training programs. This  allows the project team to increase test running of trains as part of validating consistent and reliable  performance ahead of trial running.

As outlined at the Light Rail Sub-Committee on September 29, 2023, this important milestone will also allow for an increase in the training of new diesel rail operators. New operators have been  undertaking in-class training, including on simulators, and can now increase the time spent on the  vehicles training for real-world, operational scenarios. There are currently ten rail operators who have completed their program that will help support the training of additional rail operators under  simulated train operations.

Train testing on the south extension began in winter 2022 and has since extended across the line  with a gradual ramp up of both vehicle quantity in use as well as the testing of the signaling and  train control systems. OC Transpo continues to work with TransitNext on successfully achieving  key milestones in the testing and commissioning program.

Further information on the ongoing testing and commissioning program for Lines 2 and 4 will be  shared at the Light Rail Sub-Committee on December 11, 2023.
