Wow, that is slow.
Here in Paris, in the meantime, they've started building several new lines and extensions and already opened about 40 kilometers of new extensions...
Like 22 km and 12 stations on metro line 14, all deep underground, with 2 openings respectively in 2020 and 2024, including a massive Grand Paris Express hub station.
And 6 km with 6 stations, mostly underground with a 500 meter viaduct, for metro line 11 Eastern extension.
Plus, an 8 km extension with 3 huge new stations for RER E Western extension, including one built with "mole techniques" through an underground parking garage, under a working convention and expo center between skyscraper foundations in la Défense business district and without vertical access from the surface.
And last , a 3.5km and 7 stations surface extension for circular tramway line T3b...
Since 2012, they've also opened 10 additional tramway lines with 125 km of new dual track routes. Though, of course, they started building the tramway lines that opened between 2012 and 2014 before 2011.
They've also, during this time, entirely dug the new line 16 and are currently finishing the 35 km lomg Southern section of line 15, with 16 stations, that's due to open next year...
In other words, they've already dug and built more than 110 km, or over 60%, of the Grand Paris Express underground infrastructure, plus some other extensions, while only starting construction and digging between 2016 and 2018. (First TBM launched in 2018).
Parisians feel like the construction works are taking ages, so I can't even imagine how Torontonians must feel seeing this half underground, half surface, beefed up tramway line still not open after 13 years...
Let's hope this line opens soon.

The problems appear to be due to the different caternary types in place between the above ground and underground versions. The Underground versions have been found to be much more fragile and prone to breakage compared to the above ground versions and thus causing issues with reliability. Apparently the caternary in question is a central part of the CBTC system that the line is using to automate train speeds, and only certain caternary components are compatible with CBTC, with the type that is actually compatible that is prone to breakage.
This explains why the Finch line is progressing better than the Eglinton line because they use an above ground version that does not use CBTC. Metrolinx is trying to find a solution, but because they have forced themselves into a corner with regards to the Caternary issue, they are simply patching the trouble spots and hoping that the rest of the underground caternary does not break. Calls to replace the entire caternary system apparently cannot be fulfilled because this is the only caternary that is compatible with CBTC. But if the Caternary is going to be replaced in its entirety, this will push the opening date of the line to 2026.
Oops.

The CEO needs to go. No one in project management cannot tell you when a project is expected to be completed. When someone tells you that they can only announce the opening date 3 months in advance of the date is basically has totally lost control of this project and has ABSOLUTELY NO IDEA what the team is doing. He needs to go.

Not surprised. I had a minor role at the beginning of the project & it was far more complex than originally anticipated. Every time you go underground you never know what you’re going to find & most of this project is underground. Actually the project team has done a pretty good job given the circumstances. Given that the project is late & over budget I agree with the opening date decision. Why expose the team to further criticism.
