As planned and as expected, we're in the middle of serious trial running of the system right now. Every day, well before 6:00 a.m., our partners at the TTC turn up to drive these vehicles and put them through their paces until 2 in the morning. And as at late July, TTC personnel are also now showing up at Eglinton stations to put the non- rolling stock infrastructure through its paces too. Escalators, elevators, HVAC systems, etc.
What we are finding out from this deliberate period of stress testing is that one of the issues to address collectively is vehicle availability and reliability. These vehicles are 10 years old. They're only just now beginning to run the kilometers that were intended for revenue service. And as we do that, we find out what their maintenance profile is. We get a better picture of how to keep them in service so that we can build the availability of vehicles to a level that can meet peak capacity.
We're hoping that we're a few weeks away from being able to say that we've got that kind of availability and reliability. We will then trigger the revenue service demonstration test that I mentioned last time. 30 days of running at revenue service in order to demonstrate that this system is safe and reliable when it opens.
If that works, then we will declare substantial completion of the project towards the end of September. And then we will work with both the government of Ontario and the TTC to think about progressive ramp up of service on Eglinton, itself a recommendation from Justice Hourigan's Ottawa LRT inquiry report.
So I just want to conclude by saying we are 100% doing this in partnership with the TTC. My personal thanks and that of my organization to Mandeep and his team each and every morning starting as I say sort of at 6:00 a.m. I can promise you that both CEOs of both organizations are thinking about the plan for the day, what it's going to reveal and what it means that we do tomorrow.
Reporter: So September is not off the table for a public opening?
Sir, as I told you last time, everything is dependent upon safety and reliability. I am happy that we are discovering right now the things that have to be fixed before we open this line as opposed to discovering them when the line is open. Every problem that we find today and correct in partnership with the TTC is one that will not present itself when people are riding this. It is not off the table, sir, but as I told you last time, it's always subject to making sure that the system is safe and reliable when we open.
