re: Simple question: brand new state of the art train didn't have GPS governor?

I already regret asking but:
What is fake news? That they were going that fast or that they had no governor?
What would be the motivation for lying about either one? I can see just getting facts wrong about a disaster within a day of it happening, but you specifically used the word "lie."
Eh.. don't engage him. That's just his shtick. Any time anything happens, he says "don't believe what they tell you."

I think a privately-operated superspeed train that went between cities would be pretty awesome.
The only successful way that happens is for that private company to build and maintain their own railroad. Running high speed trains over through-freight tracks does not get the job accomplished. It would be economically impossible for a private company to undertake such an endeavor. About 15 years ago, an estimation by the railroad I worked for estimated it cost $100 per crosstie to the RR when you consider labor, parts (rail, tie plates, ballast, etc.) that go into laying down that crosstie.

Because it didn't have ATC, automatic train control, the thing that automatically slows a speeding train down. Of course with this safety system you have to have sensors stationed along the way for the system to actually work. This was not the case here. Installment of this system was on the agenda for next year.
Something tells me this Amtrak engineer was not familiar with this territory seeing as to how it was Amtrak's first run on this line of track.
Something else. Is a $181 million upgrade a good way to spend money just to only save ridership 10-15 minutes in their travels? I would say that not's much bang for your buck but that would be a tad insensitive on my part when using the word bang because there was a helluva big one yesterday.
A $181 million upgrade to save every rider 10-15 minutes? That doesn't sound like a bad deal to me. Hundreds of billions of dollars of economic productivity is lost due to traffic and transit delays every year. That is something that is very rarely discussed.

Dagny Taggart would have definitely defied the anti-dog-eat-dog rule and ordered the governors be removed for maximum efficiencies, mate. Sometimes regulations are needed.
she was running her train on reardon steel which could handle the faster speeds.
engineering wins over government meddling, mate.

The speed limits (time table speed) on rail lines aren't like speed limits on highways. They're what the track was designed for and what it can handle. Going over is a serious violation and increases the chances of derailments significantly.
in other words, what i stated. limits are based on engineering limits.

Some railroads have gotten segments up and running but I have no idea what the status of this particular line is regarding PTC though. Obviously it wasn't turned on, but I don't know if that's because it isn't up and running yet or if they just opted not to use it.
why cant they use GPS in the meantime? WAZE tells me the speed limit on every street i'm on and alerts me if i'm going over the posted limit.

Apparently it was supposed to be implemented, but due to cost, the can was kicked to the following year.
So the trump tweet that had all the jimmies rustled was pretty spot on. Adequately funding amtrack could have possibly prevented this accident?
I saw it reported that this stretch in Tacoma was a new route that engineers weren't familiar with. Authorities are stopping short of calling engineers reckless, although it's hard to imagine there isn't some serious culpability on their part.

Personally, I like the idea of more rail infrastructure. I think a privately-operated superspeed train that went between cities would be pretty awesome. Imagine being able to live out in the country, needing to only drive 10 minutes or so to a high-speed train, then zip to a city that would take hours to reach by car for your job.
Sadly, it would be a massive undertaking for a corporation and I don't like the idea of the government trying to run it.
Isn't that effectively what Elon Musk is trying to do between Baltimore and New York? It's not a train, but it's still mass transit.

brand new train and an engineer driving it who had never been on this router going 50mph over the posted limit.
WHAT COULD POSSIBLY GO WRONG?

If it's all private money, spend away. Was any of it taxpayer financed? I don't know.

There's a big difference between using WAZE to see the speed limit and allowing WAZE to control the speed of your vehicle. For projects like this, automating the speed of a train that was already purchased, the bulk of the budget is actually spent on engineering work, not equipment.

If you mean the Vactrain (Hyperloop), yes - Elon Musk proposed one from DC to NYC that would take 29 minutes (which is a 4 hour drive, not including traffic). Another company, Hyperloop One, is looking at 11 different routes across the US, including the Midwest, Texas, CA, MA, etc.

I don't think traditional rails will be used, which is both good and bad in this regard. They'll likely need to limit it to the Northeast, California, and Texas due to proximity for major metro areas, but from there build out.

The train operator may have been reckless, but I doubt he saw a "Speed Limit 30 MPH" sign and ignored it because he was joyriding or trying to be "edgy" or whatever.

at the very least it could warn dispatchers the driver was being RECKLESS. it didn't have to actually do anything except set off alarms.

is it normal to go 80mph in a train that has never been driven before over routes you've never driven before?

You didn't state anything. You asked a question (Aren't those limits set by engineers based on physics?). I was answering it.

I can't tell if this is a serious question. Surely not...

There should have been a "pilot" on the train if the engineer was unfamiliar with the territory. That falls on the railroad company alone. Even if the engineer requests it the company can still refuse to give him one.
Concerning a 30 mph sign being used as a slow down signal, there is also somewhere in that train's timetable showing the exact locations of reduced speed just in case signage along the track is missing for one reason or the other.

I suppose you are going to tell us that there really wasn't a train crash or that government had the train crashed in order to deflect from some other issue.
