We’re getting closer to opening Lines 2 and 4, but before we do, we need to ensure that the system is safe and reliable for customers.
Trial Running evaluates the rail system before it can open to the public.
This stage is designed to evaluate the system’s performance, ensure safety, and confirm reliability under real-life conditions.
The Trial Running phase lasts for at least 21 days. Trial running may be extended if achieving the on-time performance target of 98.5% requires more than 14 days.
On time performance is measured by assessing on-time departures at terminus stations for both Line 2 and 4. Trains must depart within 30 seconds of their scheduled time.

When will Line 2 and Line 4 open?
We know customers are eager for the new service, and we're just as thrilled to bring the O-Train to Ottawa's southern communities. However, we must ensure quality and safety. We won’t launch until the system is thoroughly tested and reliable.
Once Trial Running begins, you'll find daily reports for Monday through Friday, detailing TransitNext daily performance from the previous day. For more details on the daily reports, please read the terms of reference .
The second phase of Trial Running will focus on evaluating various operational and maintenance scenarios. This stage will last seven days, during which we’ll simulate various scenarios that could occur in real operations, such as operational issues and service disruptions.
