It's not been exercised. There's no money allocated in the 2018 budget, based on Bombardiers poor delivery performance of the first 60+ cars.
Which is absurd, with them now producing at least 60 a year, it would only be about a year's extra delivery to get those 60 cars.
Let's see how many decades it takes now.
Though as their are court-challenges outstanding, who knows what might still be agreed to.
Also, the 60-th car isn't the only condition. There's also the car meeting certain performance standards that haven't been met yet - even if it's only minor issues with the doors.
