I do think this article has a rather unrealistic tone for what the rest of us can learn from this though.
> One advantage is that CDPQ Infra was able to take advantage of existing rights of way to create the route, rather than needing to dig costly tunnels or demolish buildings.
This is huge. In many cities where we most desperately need public transit in the US, this just isn't realistic. We need net new lines either over or underground, and no matter how you slice that they're going to need right of way allowances and NIMBY disagreements. Plus most urban settings that will benefit the most from transit will need tunnel development as part of the cost projections.
> Quebec passed a law that requires municipalities to respond in a timely manner to CDPQ Infra’s requests for permits and other forms of cooperation.
Reading about California's highspeed rail project[^1], it seemed clear that there was deep government buy-in about the end state but the interim goals were over legislated. Counties in the central valley traded their buy-in for the project to starting the line build-out in their counties, even though population centers in LA and SF could have benefited way more from early wins. One thing this article missed was that we need to set more of a precedence for transit agencies / bureaucrats on the ground to make decisions that will further the end goal and circumvent the horse-trading at the legislative level.
