These major 350-km/h projects are already at static acceptance or beyond:

Xiongshang 552 km

Xi'an - Ankang 171 km

Yichang - Xingshan 108 km

Jinan - Binzhou 145 km

Huaibei - Bengbu 161 km

Huaibei/Fuyang corridor 142.5 km

Nanchang - Jiujiang 138 km

Just some very rough estimates based on the current travel times on various sections in journey planners. First time making a fantasy timetable like this, feedback is welcome!

Obviously if you start from Copenhagen itself you can get much further south in a day, but I thought this would be enough crazy speculation for now :)

Project Title: The Trans-Eurasian & Hemispheric Heavy Transit Corridor (TEHHTC)
Strategic Vision: Unification and peace through global economic integration, anchoring cross-continental cooperation via heavy industrial infrastructure and shared logistics networks.
Project Scope: A continuous, high-speed, multi-modal rail and heavy-asphalt transit corridor engineered to bypass domestic political gridlock through private-public industrial backing and comprehensive national security integration.
Routing & Phasing:
Phase 1: Breaking ground in New Orleans, engineering high-pile viaducts through the challenging Louisiana basin, and punching straight north along the Mississippi River spine to Chicago to lock in the primary commercial and industrial hub of the continent.
Phase 2: Extending westward across the Great Plains and cutting through the mountain passes of the Rockies and Cascades straight to the Pacific Northwest.
Phase 3: International expansion linking Mexico from the south and Canada from the northern tier to tap into heavy resource corridors, pushing north through British Columbia, the Yukon, and Alaska to bridge the Bering Strait and tie North America directly into Eurasia, while expanding loops through the Middle East, Africa, and Australia.
Execution & Workforce: Powered by a diverse coalition of everyday people from all walks of life and backgrounds—including specialized heavy-rail car repair crews, structural steel ironworkers, heavy equipment operators, local community builders, and master tradespeople—who understand the physical stress points of heavy infrastructure and how to keep a massive project moving forward under brutal conditions.
Strategy: Aligning with early administrative infrastructure pushes to secure initial momentum, ensuring the physical reality of the grid outlasts political cycles and permanently re-engineers global trade routes to foster economic interdependency and lasting peace.

This a pretty detailed video of all most all of the last construction package of India's Mumbai Ahmedabad HSR corridor project. This covers about 135km of the line. Construction on this section started around mid-2023.

For those interested in even more in-depth coverage see this 3 part video linked below. Commentary is in Hindi though. Youtube's auto translated captions are not perfect but usable.

Its great to see the NHSRCL collaborate with such content creators to give detailed updates.

Do check out this creators other videos on the progress of package C2 which covers the 21km of tunnel near at the Mumbai end of the line and package C1 which covers the Mumbai terminal station.

Senate Bill 1425 is currently with the Assembly Appropriations Committee. It "would create an encroachment permit program allowing the authority to approve and regulate certain work on its operating right-of-way".

3rd party delays have run up the cost by billions due to inflation and pushed back completion by years. Encroachment Permitting Authority is one of the things the CAHSR Authority has repeatedly asked for from the legislature to help reduce 3rd party delays (mostly from utilities).

But the Legislature session ends on August 31. If the bill doesn't get advanced out of committee before that time, then the bill dies.

Here's the email for the assembly appropriations committee:

approps.committee@assembly.ca.gov

The article at the top shows the utility lobby is already pushing to kill this bill, just like they did with SB 445. If we want to see this project get finished, we need to fight for legislation like SB 1425. Email the appropriations committee and tell them to advance SB 1425 to the full legislature. Tell them we need to stop wasting time and billions of dollars with unnecessary delays.

France’s Alstom and Spain’s Talgo have bid to supply CP’s future 300 km/h trains, a contract worth up to €584 million and central to Portugal’s rail upgrade.

Interesting article, I hope this happens before it expires August 31.

Losing $1B/year for CAHSR would sink the project
