Someone tell the Town of Atherton that electric trains don't pollute. I think they're now up to 3 lawsuits against California high speed rail, at least two of which are on environmental reasons.

Are the overhead wires copper? If so what gauge? Anyone know how many lbs per linear foot of copper that would yield ? Asking for a friend

Material can vary based on the use. Something like the TGV will use a different alloy than a slower regional line. A quick search shows bronze and hard-drawn copper are frequently used. But I wouldn't rule out stainless steel.

BTW - tell your "friend" to wear their insulated gloves. They can be energized up to 25,000 volts.

More importantly you can get an electric shock, which typically means killed at 25 kV, without being even close to touching any metal. I believe something as far as 100 cms is considered a safe distance. In Europe youngsters get killed when climbing on parked freight trains. A significant part of railway traffic is electric over here, diesel is only for rural low traffic areas.

The article is not worth HN. Not even the manufacturer is mentioned.

*Building the line* has a massive environmental impact, so they're not wrong as such.

The risk of course is doing what has been done with HS2 in the UK, all the environmental damage before killing most of the project and thus no end benefit*.

* Unless you count enriching your tory donors by selling them the cancelled land secretly within hours of cancelling the project.

I was just looking at Caltrain routes yesterday wondering how there’s a route from Sunnyvale to SF that takes over 2 hours. Driving (at times) should be about 45 minutes. Didn’t make sense to me.

It's the local, when you drive you don't stop every 5 miles and pick-up/drop-off a couple dozen people :)

The bullets (limited stops) is actually really fast (~45 minutes MTV to SF).

At rush hour when it's 1.5 hours from Sunnyvale to downtown SF that's when the bulk of the bullets are scheduled and it's twice as fast as driving, plus you can have a beer ;)

All the reasonable alternatives pollute more long term. Nobody will accept the idea that they should become a subsistence farmer that never goes farther from home than he can walk (sexism intended).
