Switzerland has some really long tunnels. They just recently completed the Gotthard Base Tunnel in late 2016. With a route length of 57.09 km (35.5 mi), it is the world's longest railway and deepest traffic tunnel and the first flat, low-level route through the Alps. The main purpose of the Gotthard Base Tunnel is to increase local transport capacity through the Alpine barrier, especially for freight, notably on the Rotterdam–Basel–Genoa corridor, and more specifically to shift freight volumes from trucks to freight trains. And also, by the way, express passenger trains by cutting one hour of existing travel time.

What makes the CHSR different is who will be able to use the new tunnels. You will not see freight trains using them in California if they choose to run light weight HSR trainsets.

^ for reference the pacheco tunnel is to be 13 miles (21 km), with another smaller tunnel 1.5-mile (2.4 km).

^ Interesting.

I did not know the history behind this.

Brightline Bets on High-Speed Rail From LA to Vegas

Los Angeles Business Journal


"Plans for a $5 billion high-speed rail line to connect Southern California to downtown Las Vegas have taken several steps forward in recent weeks.

Miami-based Brightline Trains earlier this month received $200 million in private activity bonds from the Nevada State Board of Finance to help fund its planned 170-mile high-speed rail line between downtown Las Vegas and Victorville, which has a target completion date of 2023.

That follows a $600 million bond award from California announced in April..."

Please used a different thread. Not on California high-speed rail. There is existing thread.

"Q. The California High-Speed Rail Authority was established 23 years ago.
During that time China has built 16,000 miles of high-speed rail. We are still working on the first 119 miles. What are we doing wrong?"

President Xi please annex California

Here is a video flyover of the current preferred alternative for the route between Palmdale and Burbank.

This was posted on the US highspeed thread https://www.skyscrapercity.com/threa...post-170731861, but John at The Four Foot has a really nice 4-part work in progress update of the ROW with drone footage, google maps and construction on the ground from South to North, so starting with

Again, THANK YOU John at The Four Foot

Yeah those are great. He still has one more to go though.

All,

You can sign the petition. This is for high-speed rail all over America.

California HSR is Peachy
The state's rail modernization project is looking up thanks to Georgia's election results

https://sf.streetsblog.org/2021/01/0...s-look-peachy/

Feeling good

About 2 years ago I posted on this thread that Newsom's "cancel" was a political save-face stunt and CAHSR would get back to business when Trump was booted. Somehow events in Georgia now mean Amtrak Joe will take the helm with control of both houses plus a VP from California. So it's pretty unlikely that CAHSR won't get a major infusion of federal support in 2021.

^Been right there with you all along jmeck...

Tremendous news! I hope this speeds things up and we get the rail that we need

I'm agree with you. They will speeds it up and step forward. Get it done! ASAP!

Also, Elaine Chow is gone, who was responsible for that stunt back in 2017 that needlessly delayed funding to the Caltrains electrification.

We won't see any of those sorts of obstructionist games for at least two years and possibly four.

I do believe that Republicans stand a chance of winning back the House in 2022 and it's a coin flip with the Senate.

^Which is a nauseating possibility for so many reasons.
