The underground station would unfortunately be the most expensive, disruptive and complex element of the tunnel he sketched…

The project you linked (YNSE) has a price tag of $5.6 billion (i.e., not just the $1.4 billion quoted here for the „Advance Tunneling“) and is a walk in the park compared with the complexities of tunneling underneath dense downtown areas, this nation‘s busiest rail corridor and rail station and...

I suspect it‘s rather ALTO which would be reluctant to agree on such a cohabitation. For Metrolinx, track-sharing could be a welcome vehicle to unlock federal funds for measures which have massive benefit to their own services. You are describing a stretch which would be between 5 km north and...

I was solely commenting on the question whether additional tracks were necessary if a hypothetical station was to be added at Lawrence East by sharing my professional suspicion that this additional station would be less disruptive if it was located at the main tracks without any passing tracks...

Indeed, even the fastest scheduled downtown-to-downtown travel speed I‘m aware of in Europe (Paris to Strasbourg at an average speed of 253 km/h) starts rather slow out of Paris Gare de l‘Est:

I‘d like to just add the perspective of a Rail Operations Analyst to that final sentence: If the suburban train goes into a siding track, it will lose a bit of time due to speed restrictions entering/leaving that track and a lot more (maybe 2 minutes), while waiting for the intercity train to...

Thank you for reminding us of what I thought (hoped?) we had already established months ago:

I can’t comment on behalf of either party, but the working assumption at Metrolinx seems to be that ALTO would share their tracks and stop at Kennedy station…

Well, if I compare the privately-owned-and-run rail systems of Japan with the state-monopolies of ex-Yugoslavian States (like Croatia, Serbia, Bosnia or Albania), I start to doubt that state ownership of transportation systems is the golden bullet you believe it to be…

I’m a bit lost here: what exactly is the tunnel and detour we are talking about here?

Just need to purchase enough shares in CN and CPKC to obtain a controlling stake and then (or probably already before that!) fantasy has no limits… 🤣

From what I piece together from the grapevine (and should be consumed with a grain of salt), the progress blocker is not necessarily the shed itself, but the support structures underneath the tracks, which would need to get fixed before any major modifications or upgrades like electrification...

This map provokes me to circle back to the evolution of the Fulda-Gerstungen HSR line (in a more detailed way than I just did for the Hanau-Fulda HSR line in the Quebec-Windsor Corridor thread), which shows how the routes of German (if not: European) HSR projects are continuously refined...

Yes, public (!) consultations will last at least 3 years before the route can be finalized, but this is exactly the reason why they are normally done as early as possible in the planning process, so that you don't waste years in your little silo planning your route which will require substantial...

Thank you! This is exactly where I start to feel very unease with the “High Speed Rail Network Act”, which is certainly amplified by ALTO’s deeply entrenched intransparence and outright secrecy about the kind of information any individual citizen would need to assess how they personally will be...
